Abstract
A creepless snap acting bimetallic switch having flexible contact members. The bimetallic switch comprises: a bimetallic element being adapted to snap between a first mode and a second mode, the first mode corresponding to a closed position of the switch, and the second mode corresponding to an open position of the switch; a first flexible contact member disposed adjacent the bimetallic element and having a first contact portion thereon; a first terminal electrically conductively coupled to the first flexible contact member; a second flexible contact member disposed adjacent the first flexible contact member and having a second contact portion thereon, the first contact portion and the second contact portion being disposed relative to one another such that, when the switch is in a closed position, the first contact portion and the second contact portion are biased against one another by the bimetallic element to be in engagement with one another, and when the switch is in an open position, the first contact portion and the second contact portion define an open contact gap therebetween; a second terminal electrically conductively coupled to the second contact portion such that when …
