Abstract
1459941 Switch contacts; retractive switches CGE COMPAGNIA GENERALE DI ELETTRICITA SpA 7 March 1974 [15 March 1973] 10254/74 Heading H1N An electric switch is convertible from normally-open to normally-closed, or vice versa, by removing stationary contacts 3, 4 from cavities 5, 6 and replacing them in cavities 7, 8, the terminal 40b, Fig. 3, occupying the same position relative to the switch housing in both positions of the contacts. The plane of the stationary contacts Fig. 3, lies at an angle to the plane of the integral terminals, so that in either position the terminals project through the same slots in the cover 21, Fig. 5, without having to use a different cover for each position. The stationary contacts 3, 4, are bridged by bridging contact 9 movable by spring loaded plunger 15 which may be operated manually or by a machine. Cover 21 clips on base 2 by flexible slotted legs 25, 26 on cover 21 engaging projections 29, 30 on base 2. Insulating barriers 37, 38 integral with cover 21 are provided adjacent the terminals to insulate them from adjacent metal parts or from adjacent switches.
