Abstract

1446873 Switch casings SCHUTZAPPARATE-GES PARIS & CO mbH KG 21 Aug 1973 [22 Aug 1972] 39400/73 Heading H1N A fault-current protective switch has a casing 31, 32, 8 including elongate guide surfaces 26 for respectively engaging two spoil members 20 and arranged to be retained thereon by a spring loaded catch comprising a lug 19 and a slidable member 22 biased by a spring 21 to hold the casing with a part thereof, which contains a coil 2 forming part of the switch circuitry, projecting into a space 4 between the rails. An accessible rotatable switch knob 6 has a rim 62 engaging an annular surface on the inner wall of the casing part 8 against which it is biased by a sealing elastic diaphragm 9.
