Abstract

1,136,614. Thermal switches. DANFOSS A.S. 23 Sept., 1966 [5 Oct., 1965], No. 42610/66. Heading H1N. A bi-metal switch intended to be located in the windings of a machine has normallyclosed contacts which are opened by ambient heat and which are held open by a glow discharge between the contacts. The bi-metal is substantially insensitive to other heating effects.
