Abstract: A snap action thermostatic switch assembly of the type having a bimetal arm and an omega spring. The assembly has a fixed contact and a pair of resiliently mounted movable contacts on opposite sides of the fixed contact. The movable contacts have lugs and the bimetal arm has an actuating element which engages these lugs to move one contact or the other away from the fixed contact. The bimetal arm has a displacement range so that the actuating element thereof separates from the contact lug of a movable contact that is brought into engagement with the fixed contact. With this construction the tendency of a movable contact to rebound is minimized by reason of the mass associated with a movable contact being reduced the instant the movable contact touches the fixed contact.
