Abstract
1,133,638. Thermal switches. DANFOSS A.S. 9 Sept., 1966 [5 Oct., 1965], No. 40408/66. Heading H1N. A normally-closed bimetal switch having its bimetal in series with the contacts is heated by current therethrough and is maintained open by a glow discharge. Heat for opening may also be provided by an auxiliary heater. Screens may be provided to prevent the deposition of metal vapour.
