Abstract

1372927 Momentary contact switches PLESSEY CO Ltd 16 Jan 1973 [19 Jan 1972] 2682/72 Heading H1N A momentary contact push button switch for keyboard applications has a movable contact 4 pre-bent from springy strip with one end turned to bear on a concave cam surface 7 of a push button 3 and which bows to make contact with the bias spring 2 serving as a fixed contact when the push button is initially depressed. On further depression, the end of contact 4 springs into cavity 8 and contact is broken with a snap action and upon release the strip restores to the position shown without making further contact. Contact arrangements for momentary break or changeover action can be provided.
