What do you call the following type of switch? And where can you get some?
I will do my best to explain it. I don't have a picture of one because I can't find it on the Internet.
The switch consists of two stiff, formed wires in a plastic housing intende d for thru-hole PCB use.
The first wire comes straight up and has an inverted J-hook at its end. The second wire is about 3/8" away and is "springy".
When the second wire is pushed down and under the J-hook of the first wire, the contact is closed. Otherwise, it is stiff enough to "ride" above the J-hook by a pretty good distance (at least 1/4"), which is enough to ensure an open circuit. You have to deliberatly engage the two wires to meet (vi a the the J-hook) in order to close the circuit.
I vaguely recall seeing one of these on a commercial burglar or fire panel many years ago, but I can't recall which one(s). The switch was used to pu t the panel in program mode, I think? Thanks!!
