Abstract

1,223,306. Thermal switches. ELETTROTECNICA VEBE S.p.A. 12 Nov., 1968, No. 53561/68. Heading HlN. The spring contact strips 3A, Figs. 1, 2 of three independently operated bi-metallic switches are arranged in an equilateral triangle within a cylindrical housing A and are actuated by snap-acting bi-metal discs 1A engaging slidable pins 2A. The spring contacts 3A are fixed to terminal member 4A or 11 projecting from the casing and interconnected by a starshaped spider S. The three fixed contacts 51A are mounted on terminals 6A projecting from the housing. Seatings Se and Se<SP>1</SP> of the terminal 4A, 6A are separated by a rib N of the casing.
