Abstract

1,076,837. Thermal switches. ELLENBERGER & POENSGEN G.m.b.H. July 6, 1964 [Out. 26, 1963], No. 27808/64. Heading H2B. A relay comprising a bimetallic blade 6 actuated by a heater coil 8 to snap a contact 12 into engagement with a contact 13, adjustable by set-screw 15, is provided with additional contacts 23, 24, 26 operated by means of a slide member 20. The additional contacts, which may be used for indicating the condition of main contacts 12, 13, are enclosed in a housing 2 which may be secured to or integral with the main housing 1. Two transparent covers or a common cover may be secured over both housings by means of a rivet 30<SP>1</SP>. The bimetallic strip 6 may carry a contact co-operating with a further fixed contact for shorting out the heater 8 to prevent overheating (Figs. 4, 7 and 9, not shown). The main contacts may be rearranged to break instead of make (Figs. 3 and 4, not shown) or a change-over arrangement may be provided (Figs. 8, 9 and 10, not shown). In a modification (Fig. 2, not shown), a T-shaped lever, pivoted on rivet 30<SP>1</SP>, replaces the slide member 20.
