componentsidentificationradio
I am trying to identify this component from a circa 70s AM/FM radio. It was attached to a flip clock, which makes me think that it is a magnetic device responsible for the "flipping" action of the clock.
The three terminals are labeled N.O., COM, and N.C., in that order. Google search isn't being my friend right now, and is giving results which seem completely unrelated.
It is a thermostat as Dave Tweed and Kaz noticed.
I got a similar one and it has the temerature written on it:
Looks like a late 1950's/early 60's Germanium transistor. Use a multimeter in diode testing setting to figure out where the PN junctions are. You should see some 0.3V forward voltage across these, and in reverse, the multimeter should display an open circuit.

That is a microswitch. The red button on the edge throws the switch when something presses it. The contacts are labelled Normally Open, Normally Closed, and Common.
