Abstract

The bimetallic thermal switch is provided with two bimetallic convex discs (26, 28) contained in a metal cap (42) of a tight container (10) made of insulating material, the bottom wall (12) of which retains sets of contacts (18-19, 18'-19') connected to related terminals (14-15). Each of the movable contacts (19, 19') co-operates, by means of a link (24, 25), with the respective bimetallic disc (26, 28). The operating connection between contacts (18-19, 18'-19') and their respective bimetallic discs (26, 28) is effected by push rods (24, 25) each of which is provided with appendixes (24a, 24b, 25a, 25b) which are off-set with respect to each other so that the top ones (24a, 25a) engage the substantially central zones of said bimetallic discs where appendix 25a freely crosses a hole (27) in the bimetallic disc (26) contiguous to the sets of contacts (18-19) and (18'-19'). An elastic rubber sealing member (40) is retained in an annular channel.
