MULTIPLE PUSHBUTTON SWITCH

摘要

A multiple pushbutton switch is disclosed in which each pushbutton actuator has a rotatable cam mounted thereon that interacts with one or more lockout members positioned alongside of the actuator in the same plane as the cam. The interaction between the cam and the lockouts is such that one group of the pushbutton actuators can be depressed simultaneously while a second group of the actuators are blocked from simultaneous depression with the first group. Furthermore, a pushbutton actuator can be shifted from one group to the other merely by rotating the cam thereon to a different position. - i
