Abstract

1311706 Retractive switches; switch contacts J BECK 3 Dec 1970 [15 May 1970] 57563/70 Heading H1N A switch, suitable for operation by a window, for example in a burglar alarm system, comprises an insulating block 20 having a recess 30 into which two contact posts 25 and 26 extend, and a unitary blade-like spring member having one end portion 65 anchored in the block to resiliently engage one contact post 25 while the other end extends out of the recess in the form of a tongue 61 which is bent to form a V-shape with a base portion 64 to provide make and break contact with the other post 26 in response to external engagement of the tongue 61. The posts 25 and 26 are preferably screws to which external connections (13, 14, Fig. 4, not shown) are secured, and a cover (40) is fixed to block 20 by riveted eyelets through which mounting screws (50, 51) pass. When the window 2 is opened the tongue 61 is released and the part 62 engages post 26 (Fig. 5A, not shown). Alternatively the blade may be assembled such that part 62 passes around post 26 and is held in contact therewith (Fig. 6, not shown) by the window 2, the switch then being opened when the window is opened (Fig. 6A, not shown).
