Abstract
1398648 Momentary contact switches ALCO ELECTRONIC PRODUCTS Inc 28 Sept 1973 [3 May 1973] 45410/73 Heading H1N In a momentary contact switch in which at least one movable contact 16, Fig. 2, is engaged with and released from a fixed contact 14 during a single stroke of the actuator 28, 30 the movable contact 16 is mounted on the end of a resilient conductive wire 18 and is cammed away from the fixed contact 14 by a cam face 38 on the actuator rod 28 until the wire 18 passes over the end of the cam face 38 and flies inwards over face 40 to be carried by its own inertia past its normal rest position to momentarily engage the contact 14 before returning to its normal rest position. On release of the actuator 28, 30 it retracts under the action of its return spring (34), Fig. 5 (not shown) so that the face 40 pushes the wire 18 up a fixed wedge face (32) on the housing 10 which forces the wire 18 outwards until it is returned on to the cam face 38. In the example a pair of contacts 16, 17 is operated simultaneously for engagement respectivelywith two fixed contacts 14, 15.
