DP3T Switch?

Check out several on this page:

Digikey has plenty to choose from. E.g., 0.1A/12V slide On-on-on DP3T for ~$1. Products -> Switches -> DP3T -> Slide -> DP3T -> etc

Maybe I don't know it's played, but I get "No records match your search criteria" ...Jim Thompson

I was looking for a 6 pole, double throw relay with 48V coil to replace some that went flaky in our elevator control panel. They're obsolete and if you can find them at all, run about $75 each. Found some with a different footprint and may have to make an adaptor board... This is for the elevator in my office and I'd just as soon replace the entire rack of clackedy-clacks with a simple PLC (if only the maintenance company hadn't stolen the system wiring diagram).

Did you try it my way instead of a direct search?

--- You can only click one thing at a time and then click the "apply filters" box.

That'll narrow your choices down further, and to narrow them more and more do the same thing over and over.

For example, if you click on "On-On-On" in the "Switch Function" box and the click the "APPLY FILTERS" button, that'll eliminate all of the other switch functions on the next page and let you choose the next thing you want to filter on.

If you click on "DP3T" under "Circuit" and then click "Apply Filters" Finally, if you click on a manufacturer and "Apply Filters" on the next page you'll get to where you need to be.

I chose CW Industries because I like their stuff, and the next page shows their offerings.

The first entry isn't bad; 125V @3A for $0.78 qty 1.

Why not use 3 X DPDT or 2 X 3PDT?

Should be a lot cheaper than $75...

Here's a pretty nice one; DPDT contacts rated for 250VAC @ 5A, 48V

11mA coil, @2.99 each, qty 1.

$9 VS $75 is pretty much a no-brainer, huh?

Check out several on this page:

-------- None of those are DP3T. The sliders only bridge the nearest two contacts and do not function as the OP requested.

Are you another GymieBob / Josepi troll moron?

OK. I guess I didn't understand that you apply one "filter" at a time :-( ...Jim Thompson

You may have some legal problems with an elevator. Better check that one out first.

You are probably smarter than the morons at the elevator service but some regulations will apply there.

The instructions are on the filter pages right under the "Search

Ermmm...

The SSW-54 and the SSW-64 are DP3T.

Hmm... I see. I mean, those *are* "on-on-on" "DP3T" switches

but I expect you're correct that they're not what Jim is after given that he was thinking toggle switches as well.

I'll be interested to see if we can find a DP3T switch of the kind Jim is after; seems like it is pretty unusual.

I would be extremely reluctant to f*ck with the design of an commercial elevator. A stuck contact, for example, might do Bad Things, and there could be consequences:

That said, fairly recently I did modify the design of a residential elevator somewhat (they didn't do a very good job, as it turns out) but the regulations for residential elevators are essentially nonexistent, and I'm comfortable with assuming the liability for my changes in any case. The relays used to switch the motor etc. were at least quite robust and were not the source of the problems (more of a symptom when they chattered).

Jim asked for _either_ a slide switch or a toggle switch, so the DP3T
ones you showed were fine.

Toggles are harder to find, but there are some out there.

Here's a few:

http://www.mouser.com/Electromechanical/Switches/Toggle-Switches/_/N-5g2j?P=1z0z2o3&Ns=Switch+Function%7c1

Come to think of it, I'd just look for a rotary switch, e.g.,

...but it appears there are some toggle switches that meet the bill as well, e.g.,

Intriguing...

What search criteria are you using?

I selected DP3T and ON-ON-ON, then push "apply filters," and got 93 products on 4 pages.

I'd suggest Mouser because, in my experience, they're usually cheaper than Digikey.
