ABSTRACT:
A switch assembly has two rows of pushbutton switches and a rocking plate in between the two rows having projections engaging the switches for preventing the switches of one row from being depressed when any switch in the opposing row is depressed. The rocking plate is pivotably mounted on a shaft such that it can be axially displaced to release the projections from the switches and allow switches from either row to be actuated simultaneously.
