Abstract
A thermal cutoff having a mushroom-shaped floating contact member with an enlarged head and an elongated shank. The outwardly facing end of the enlarged head has a centrally located depression for reducing the area of the head end surface that engages a sliding contact for the purpose of increasing contact pressure and thereby reducing electrical resistance. The shank has a necked-in terminal end portion to facilitate assembly by minimizing the possibility that the shank end will hang up on a bushing that receives the shank. The head is enlarged sufficiently to accept a straight coil spring as well as a tapered coil spring.
