Abstract
A thermostatic switch is shown in which a movable arm mounting a movable contact and a snap acting thermostatic strip disc are cantilever mounted with the disc adapted to cause the movable contact to move out of engagement with a stationary contact at a selected calibration temperature by engaging the movable arm and moving it and concomitantly the movable contact away from the stationary contact when the disc snaps to its opposite surface configuration.
