Abstract : The patent describes a meltable plug radiation switch having a meltable uranium alloy plug which forces the ends of a snap ring apart and into contact with a pair of spring clip contacts to complete a circuit. Through exposure to radiation, the plug melts, thereby allowing the snap ring ends to come together breaking the circuit. This invention relates generally to a switch which will activate a device such as a signaling device on a power plant when the neutron exposure exceeds the predetermined threshold level, thereby preventing damage to the power plant which would normally occur due to such excessive neutron exposure.
