Abstract

A snap-acting thermally responsive actuator comprises a bimetal sheet having a U-shaped aperture defining a tongue, the sheet having been deformed to a domed configuration in a die pressing operation so that the actuator reverses its curvature with a snap-action with changes in temperature. The actuator may carry an electrical contact and have a high electrical resistance so that currents of 2 amps through the actuator heat the actuator to its operating temperature. The electrical resistance may be increased by forming apertures in the actuator.
