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

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

Hope this helps.

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.
