Abstract

1512519 Retractive switches LUCAS ELECTRICAL Ltd 26 Aug 1975 [12 Sept 1974] 39741/74 Heading H1N An electrical switch includes a movable contact spring defined by a loop 21 connected to first and second limbs 22, 23 engageable with first and second fixed contacts 13, 14 upstanding from a base 12 and a rotor 17 for moving one of the limbs 22, 23 into or out of engagement with its associated contact 13, 14. In one embodiment, the rotor 17 is integral with a spigot 18 encircled by a hairpin spring having two limbs 22, 23 biased into engagement with the fixed contacts 13, 14. Upon clockwise or anticlockwise rotation of the rotor 17 by a lever (16) (Fig. 1, not shown), one of the limbs 22, 23 is moved out of engagement with its associated fixed contact by a portion 17alpha of the rotor 17. The switch may be used to control the brake lights of a vehicle, the lever (16) being associated with the brake pedal. In another embodiment, one of the limbs 22, 23 is movable by the rotor 17 into engagement with a third contact 25 to constitute a changeover switch. In a further embodiment, only one of the limbs 22, 23 is positioned between the fixed contacts 13, 14, to constitute a normally open switch, movement of the rotor 17 causing the other limb to move into engagement with its associated contact.
