Abstract

1,239,581. Retractive switches. JOSEPH LUCAS (INDUSTRIES) Ltd. 17 Dec., 1968 [12 Jan., 1968], No. 1832/68. Heading H1N. A switch comprises two body parts 16 and 11 respectively carrying a moving contact 19 and a fixed contact blade 15. The part 16 is of conductive material and has a portion 17 which is an interference fit within the part 11, moulded of synthetic resin. During manufacture the required contact gap is readily set by holding the plunger 18 depressed against the action of spring 21 by the amount it will be depressed when in use, and then forcing the body part 11 towards the part 16 until a test circuit between terminal 14 and the part 16 is established; the plunger 18 is then released, leaving the desired gap between contacts 19 and 15. The interference fit is such that no other locating or securing means is required.
