The kind of switch I’m looking for is similar (though obviously not identical) to the kind you see in movies where the guys stick their keys in a lock and turn it to be able to launch nuclear missiles. Or sort of like an ignition switch for a car, but not, again, obviously, for such a thing. I’ve seen them used on various equipment over the years to lock out power sources so that no one can run a machine. Anybody know what they’re called and where I can get one?

They’re called [Keyswitches](http://rswww.com/cgi-bin/bv/rswww/searchBrowseAction.do?N=0&Ntk=I18NAll&Ntt=keyswitch&Nty=1&D=keyswitch&callingPage=/browse/Campaign.jsp&BV_SessionID=@@@@0405217777.1164278721@@@@&BV_EngineID=ccchaddjfjmkldfcefeceeldgondhgi.0&cacheID=uknetscape&Nr=avl:uk)

I’ve always referred to them as “key-lock switch” or “ignition lock/switch”.

[This plays agrees.](http://www.electronicpartsforless.com/storefrontprofiles/processfeed.aspx?sfid=100806&i=5327640&mpid=36&dfid=1)

Grrr… “place”. That’s what I get for trying to answer a question at 3AM after ranting about theatre for a good hour.

And then you can [put one of these over it](http://www.jaycar.com.au/productView.asp?ID=ST0578&CATID=&keywords=missile&SPECIAL=&form=KEYWORD&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATID=), and _really_ make it look like it’s for launching a missile.

[/QUOTE]  
Check them out at the nearest electrical supplier. The bigger they are the better the selection available. They can order one from catalog(S) too.

I have accounts with both electrical suppliers and locksmith equipment vendors for that sort of stuff. They are available in a variety of functions-key retained in all but off, momentary, spring return, and so forth. Ordinary and biaxial keyways, too. Send me an email, **Tuckerfan** and detail what you’re seeking.

As a bit of a hijack, I have a question about a different kind of switch. Does somebody make a cheap box (not something that goes in the wall) that turns off an outlet via a remote control? It’s so I can turn the light off from bed. Bonus points if it resets to on, when I turn the wall switch off, so I can turn it back on with just the wall switch.

[X10.com](http://X10.com) is much reviled for its ongoing “spam” once you register or order, but they have what you you sem to want, at a decent price. A lot of people also take advantage of their gimmicky bulk sales, and resell on eBay.

I’m not a _huge_ fan, but all in all, I’ve found that their products usually meet my needs, and are IMHO underutilized. “X-10” refers to the underlying technology that goes back to the 70s (at least) when I first started using them as a teem (It was pricey then, but yard sales around here often sold them, because the nouveaux-riche quickly learned that they actually had to _install_ them for them to work.
