CA 2145121

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.

Disjoncteur thermique ayant un élément de contact flottant en forme de champignon muni d'une tête élargie et d'un corps allongé. L'extrémité, faisant face à l'extérieur de la tête élargie, comprend une cavité centrale de façon à diminuer la partie de la surface d'extrémité de la tête qui engage un contact à glissement dans le but d'augmenter la pression de contact et, par conséquent, de réduire la résistance électrique. Le corps comprend une partie d'extrémité à rétreint afin de faciliter l'assemblage en diminuant la possibilité que l'extrémité du corps bloque sur une douille qui reçoit le corps. La tête est suffisamment élargie pour recevoir un ressort hélicoïdal droit ou effilé.
