Phase Linear 700 power switch

[wattsabundant]

I get 2-3 emails a week from people looking for a power switch. does anybody have a source for either type that was used.? I am looking at options to use the switch to drive a relay or a triac.

The microswitch clusterfuck you wouldn't want would you?? The other's I think Ed had the only stash of those.

Also Don, i need 2 more 700 boards, and 2 more 400's.

If you're going to drive a relay, why not a rotary wafer type??

I think (?) I've looked at this before and there is a clearance issue with the meter board. The microswitch is readily available if you want to drill out the rivet to get the old one out.

If you're looking at a single deck they can get pretty small, especially if it's a low current application.

typically the small ones mount in a 5/16 hole. The original is 3/8.

Hi Don, have a look here: http://www.leviton.com/OA_HTML/SectionDisplay.jsp?section=41548, product code 90572, or similar http://www.sourceresearch.com/nte/nte-pdf.cfm?pdfpage=switchpage45.pdf... Best regards!

Nice find Przem. Looks like it might work.

These would work except the knobs for most 700"s are a push on type with a "D" shaft. I've never been able to modify a round shaft into a D shaft and have it work and look right. Very labor intensive.

Were these amps designed by Greg Kinear (sic)?

Broken car stereo donor perhaps?

Got in touch with friend repairing McIntosh gears here (i.e. in Warsaw). He indicated one more option: http://www.analogmetric.com/goods.php?id=1164. Slightly less than 3/8'' but D-shaft type as a bonus ...

Don, a Dremel with a drum sanding attachment and in two minutes it can be DAMN close.

I've already tried it on aluminum shaft. Has to be almost perfect or knob wobbles. It's a big headache.

Won't argue with that, but at least it's doable. Do you shake a lot??
