Punchout Button

wbassett:

I'm looking for a Punch Out button, the big spring button in the lower right corner.



Anyone know where I can buy something like this?

iscariot:

I think I've seen something like that for industrial purposes like operating lifts, mounted on walls and the like. 

wbassett:

yeah I have seen similar buttons in our server bays for the emergency power down kill buttons. 

Does anyone know where we can buy them?

I can get the cp for $60, I'm just trying to determine if I could build it cheaper.

RandyT:


FWIW, I've seen a number of these types of switches on industrial equipment, but never with a big, heavy spring under it like appears to be the case here.  If that's what that is, then it's likely a special mod of the aforementioned industrial buttons.  Those buttons usually aren't cheap either.

More Info:

These buttons are called "Mushroom Head" or "Mushroomhead" switches.  You want the momentary type, which are a little less common than the twist or pull type emergency stops.  If the blue one on that panel has a big spring under it, it's possible that it was a retrofit of push / pull to turn it into momentary.  If you get a regular momentary, you shouldn't need to worry about the spring.

But again, they run about $30 each, so you might just be ahead of the game by buying the panel.
