rocker switch
The switch on my Kenmore vac failed. It appears that a replacement from
Sears would cost more than $20. A replacement switch must have the right dimensions for the body and terminals. Is there now an online retailer with a wide selection of fully described electrical switches? Choreboy |

Honestly...by the time you dig through a dozen websites, pay single unit
pricing, pay for shipping, handling, and insurance, $20.oo really isn't out of line. As well, Kenmore items usually use custom components for switches, so I doubt that you will find a replacement.

That would make sense if I were being paid to fix it for a customer.
It's my backup vacuum. I don't want to put a lot of money into it and I can afford to check websites at my convenience. A few years ago the computer board for my HVAC failed. It would have cost $200 to $300 to have it replaced. I found an online supplier with a good inventory of well-described parts and did it for $20, including spares. They have turned away from retail customers. Before that I used a paper catalog with a good inventory of well-described parts. They dropped their retail service. If I found a good online retailer, the switch and shipping might be under $10 and it could be as quick as ordering from Sears. I might end up spending more than $20 for my order, but that would be because I'd spotted other goodies.

Along with this attribute it would be advantageous if you developed your skills at component researching as most others who are engaged in electronics development/repair have done. I've been researching electronic components for 33 years. During that time others have often recommended distributors. You're the first to tell me, "That's for us to know and you to find out." While paper catalogues are nice to have they are costly to produce and need constant updating. Can you tell me why vendors of electronics parts send me paper catalogs because I ordered online? Anyway, I'm talking about a time before there was a www. You have the perfect alternative right in front of you in order to help you to find a suitable switch. It's not a perfect alternative. Shopping on the web can take much longer than from a paper catalog. When you seek a precise description or try to order you may find that a vital function doesn't work with your browser. I am sure that any number of suppliers such as Allied, Mouser, Digikey etc will have something suitable, AND, they all have easily searchable on-line catalogues, often with pictures. Even if no picture is supplied they may give the manufacturers name and you can then go to the manufacturers website and get further info from there. Kim said digging through a dozen websites would take a lot of time. I agree. That's why recommendations are valuable. It seems to me that executives at parts distributors sometimes decide they want only customers who buy in lots of a thousand or more. They put up obstacles to discourage small customers. Allied did that 25 years ago. Until ten years ago, Digikey was my favorite source. Then the cost of small orders became unreasonable. I think they were starting to get a lot of small orders over the web, and they decided it was a nuisance. For awhile I had a good time with Carlton Bates. If I needed something as small as a few diodes, they'd drop them into an envelope and charge me only a small handling fee. A problem with online ordering is that there may be no promise about shipping. They shocked me by putting 30 cents' worth of diodes into an insured box that shipped for ten dollars. I got no assurance that they wouldn't do it again. It appeared that they did not want my business. Google is your friend.... Google has never done very well showing me the names of distributors who encourage small customers.

I didn't expect so much assistance. I posted the picture right away. I noticed it's marked Eaton 9221. Yes, but with OEM items (as your rocker switch seems to be) it is almost impossible for others to provide recommendations unless we know full specifications of what you are looking for, as well as a picture. It doesn't have to be a rocker. A DPST good for 6 A at 125 V should work fine. If the terminals are the wrong size I can solder. The base plate needs to be about 12.8 x 27.4 mm. It seems to me that executives at parts distributors sometimes decide they want only customers who buy in lots of a thousand or more. They put up obstacles to discourage small customers. Allied did that 25 years ago. I believe Allied is now part of the RS Components group and they specifically pride themselves on small quantity sales. Admittedly the price may be higher but if you only want one or two instead of hundreds then the cost is worth it. I have an account with RS and their service even for one-off is very good. If they don't have it locally it will be sent overnight from another state. If it isn't in Australia it will be obtained from UK within a week. Back around 1980, a mail-order customer would send a check. The vendor would give the check time to clear, then mail the merchandise. As I recall, at the time, Allied required a customer to set up a corporate account. I saw no reason for it except to exclude small customers. Whenever I have tried to use Mouser or Digikey they want exorbitant freight rates even for small items weighing less than 100gms packed. I might buy US$50 worth of components and they want US$50 to send them out. It is simply not economical. They simply won't use USPS because they have contracts with the big freight companies such as Fedex etc. I generally have far better luck and lower freight costs when dealing with UK suppliers. Because you mentioned Digikey in your last message, I checked. They charge shipping plus $5 handling for orders under $25. That's what they were doing 15 years ago. As I recall, their terms were less reasonable at some point in the mean time, which is why I quit ordering. If shipping a small order in the US costs $6, a small customer can choose goods priced at $25 and pay only 24% extra, or $31. But is it fair that he would pay more ($35) for a smaller order ($24)? With web orders, I suppose the paperwork for an order doesn't cost much because the customer types the input. Suppose in the morning somebody has ordered three battery packs totaling $30 to repair three cordless drills. The stockboy carts the basket with the list around the shelves, drops in the three items, and sends the basket to shipping, which bills another $6. The company doesn't bill for handling. Suppose in the afternoon the same three items are ordered, but this time it's three customers each repairing one drill. The stock boy puts three baskets on his cart and drops in the same three items. This time the company bills $15 for handling in addition to the $6 each for shipping. That sounds discriminatory. Looking at how many orders are slightly more than $25 and how few are less, an executive might conclude that this policy increases sales. That's not the whole story. Suppose the busy customer finds he needs an $11 item to get something working. With $6 shipping and $5 handling he'll pay double unless he orders more. He has a dilemma: pay double or stop what he's doing to think of, find, and order $14 worth of other stuff. It makes ordering less convenient. Over the years he's likely to accumulate items he ordered in a hurry and found he couldn't use. This could discourage customers. Google has never done very well showing me the names of distributors who encourage small customers. That's where the experience comes in. After a while you get to know the companies who will. All it usually takes is an email to find out. You led me to a breakthrough. Googling Digikey turned up Ralph Stirling, an engineering professor with a list of electronics distributors. I suppose he has found them reasonbable for the small customer. Choreboy |

I didn't expect so much assistance. I posted the picture right away. I noticed it's marked Eaton 9221. I just checked a.b.s.e and there is a post re the Eaton 9221. Thanks. It looks like a pcb mount DPDT switch with long pins. The terminal pins on one side of each pole have been cut off so it acts as a DPST with no centre position. It seems to me that the oem specified mounting plate has been added to suit the Kenmore vac. You won't find one with the special mounting plate and this element seems to be the critical component. However, you may find one you can modify. The best you will probably find is something like this NKK M series rocker http://www.nkkswitches.com/pdf/MrockersFlatFrame.pdf I doubt that you will find any off-the-shelf switch these days with long pcb pins so you will have to extend the 0.25" long pins/lugs yourself. That should not be a problem though. I reckon you might be able to use a M2022-TY-W-01-J-A (refer to tech data). The mounting plate on the TY is 12.8 x 41.3 so you should be able to trim it to suit. I specified the solder lug terminals so you can easily add wires to lengthen them or you might specify the pcb pins. The unused outer pins/lugs can be left alone or cut off to suit. Now the only problem is where to get it. First port of call would be to try the NKK distributors and reps http://www.nkkswitches.com/NKKReps.asp Hope this helps. Ross H Thank you! M2022-TY-W-01-J-A looks like a good choice. I could even get something functionally the same as a 9221, M2024. I forgot to say the old switch says ON ON ON. I didn't know what to make of it. It means SP3T. I wouldn't have guessed it because what I need is a variation of DPST. Well, what NKK calls SP3T is really a variation of DPDT, with a center position where the poles are thrown opposite ways. If I clip two terminals I'll have what I'm after. Now I have three choices: buy an NKK M202x, install a generic switch on the vacuum cleaner case, or follow sensible advice and get the OEM switch from Sears. I'll see how hard it is to get an NKK. I don't know if Sears went out of its way to use a hard-to-match switch, but it reminds me of Henry Ford. He's known for developing a car that was cheap to produce, but his first concern was making it cheap and easy to repair. Before the Model T, drivers depended on OEM parts and factory trained mechanics. If you didn't have plenty of money and stay within towing range of a major dealer, you were better off with a horse.
