Abstract:

One or more switch apparatus for controlling a digital display of a changing function each include stationary and movable contacts and an actuator having a rest position and movable longitudinally in opposite directions to second and third positions. Cam structure is supported on each actuator to interact with a follower carried by each movable contact whereby different conditions of switch operation may be indicated by the position of the actuator relative to the movable contact. Biasing structure intercooperates between each actuator and a support for biasing the actuator toward the rest position from at least one of the second and third positions. A latch, also, intercooperates with each actuator to latch the actuator in one of the last-mentioned positions.
