Abstract

1,176,127. Inert switches. H. SZIGAT, [trading as HERBERT SZIGAT WUPPERTALER SCHLUSSELDIENST]. 24 Jan., 1968 [24 Jan., 1967], No. 3822/68. Heading H1N. [Also in Division G4] A switch for a burglar alarm (see Division G4) has a metal casing 11 fixed to a wooden door frame and an insulating plunger 8 biased by a spring 9 and carrying a metal plate 13 arranged so that deformation of the striking plate 2<SP>11</SP>, in an attempt to force the door, allows plate 13 to contact the metal casing 11. Fig. 8 shows an alternative arrangement comprising spring-biased contacts 18, 19 mounted on an insulating plate 17 and arranged to be mounted inside a metal door frame so that the surfaces 18<SP>1</SP>, 19<SP>1</SP> of the contacts may be bridged by the tongue of the bolt on deformation of the latter if an attempt is made to force the door.
