Abstract
An electrical switch comprising a housing, and spring supported in the housing. The spring is made from resilient, flat material and carries a contact at each end thereof, each contact being adapted to engage a respective counter-contact carried by the housing. Two spring tongues are formed on the spring and are supported on support bearings under stress so that a contact can be snapped out of engagement with the corresponding counter-contact upon actuation of an actuating member which engages the spring. Preferably the actuating member is temperature-sensitive or is connected to a temperature-sensitive member so that the switch may be used as a temperature-sensitive switching element, thermal relay or thermostat.
