Hi
Unless I am mistaken the yellow thing is a heat coil protector that I saw used to protect strowger switches on 50 volt exchanges. As the coil in the device heats up with excess current through the coil the solder holding the pin in melts and the spring in the mount pulls the pin out of the body.
Regards
Ian
