Abstract
A thermal switch having a temperature sensor formed of a thermal bimetallic nap disk, the temperature sensor cooperating via a transmission member with a contact system which has a contact carrier bearing at least one movable contact, the movable contact resting under spring force in its closed-circuit position of rest against at least one fixed contact. A locking member is provided which, upon a temperature-caused movement of the transmission member, is displaceable under spring force in the direction towards the transmission member at least approximately perpendicular to the direction of displacement of the transmission member and holds the contact carrier in its open-circuit position after temperature-caused movement of said support.
