Abstract
A thermostatic switch construction including a housing having a switch arm mounted for movement inside. A bi-metallic disk is mounted in the housing and movable in response to temperature change with snap action between two positions of stability. A switch arm actuating plunger is slidably mounted in the housing with its lower end adapted for contact with the bi-metallic snap disk. A bi-metallic disk mounting assembly is provided in which the disk is mounted. The disk housing serves to isolate the bi-metallic disk from contact with any part of the switch housing. The bi-metallic disk housing assembly is comprised of an aluminum platform member and an aluminum cup-shaped cup member mounted thereon to provide an enclosed space in which the bi-metallic snap disk is mounted.
