Multiple key switch

Two identical toggle springs of a snap action switch are inserted in the same knife-edged bearings and are spaced apart in the region of their clamping locations and are activated by the same plunger. There are two control arms connected to the toggle springs each having a movable contact. The relative distance between the control arms is limited by a lost motion buffer. Stationary contacts are positioned above and below the movable contacts. The control arms are actuated by the plunger and move in the same direction as the plunger establishing contact between one of the movable contacts of the control arms and one of the stationary contacts.

Snap action miniature switch

A snap or toggle switch having two sets of fixed contacts with a bridge normally resting across one pair of contacts but traversing toggle-fashion to the other pair of contacts when an actuating member is depressed. Toggle springs extend from the actuating member to the bridge, both the said member and bridge being flat and extending at right angles to one another. The actuating member operates a lever which forcibly separates fused contacts.
