very high current DC switch
Does anyone know where I can get a reasonably priced ($30 or less)
switch that can handle at least 200 amps at 13.8V? -- Chris W KE5GIX Gift Giving Made Easy Get the gifts you want & give the gifts they want One stop wish list for any gift, from anywhere, for any occasion! http://thewishzone.com |

Car starter solenoids, battery vehicle contactors etc? Just a thought, DC switches are getting rarer by the year, we use some Schneider Group switches that are fast breaking but way outside your budget.

... Have you thought of contactors? As I recall, contactors are rape. Hell, the MOSFETs to do that (say, 8 x IRFZ46N, maybe $10) are cheaper than the $1/amp I recall advertised. YMMV.. Tim -- Deep Fryer: a very philosophical monk. Website: http://webpages.charter.net/dawill/tmoranwms |

Tim We pay £18 or so for a 180A rated 28V DC continuously rated coil, or higher/lower price depending on output. We make large industrial chargers for the rail industry and use these for output cutoff. Have a look at Albright International's website: http://www.albright.co.uk/ We use the SW80, SW180, SW200 and SW201 (SW201 has Change-over contacts) If any of those meet your needs, we can probably help source some in small numbers for you or they may have agents over in the USA. We only use 28V DC continuously rated coils (most other voltages are available) and have SW80 and SW180 on the shelf in the stores here.

Momentary: Starter solenoid (they usually have a limited duty cycle) Sustained contact: Industrial power contactor (Relay) Battery Selector switch as used on Boats -(usually four position Battery #1, Battery #2, Both, Off) Check an auto parts store for a battery switch - usually designed to mount on the battery terminal to break contact to prevent loads and leakage from running down the battery while in storage, or to prevent vehicle theft. A Big Old knife switch - scarcer than hen's teeth, but relatively easy to make. ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |
