ABSTRACT:
A multi-unit switch assembly has a single housing which is divided into a plurality of compartment for respectively accommodating therein a corresponding number of switch mechanisms. Each switch mechanism includes contacts and an actuator rockable within the housing for closing and opening the contacts. Each of the actuators is provided with a spring catch for detachable snap connection with each of operator handles which correspond in number to the number of the switch mechanisms and positioned exteriorly of the housing and thus rockable together with the corresponding actuators for contact closing and opening of the individual switch mechanisms. With the detachable connection of the handle and the actuator in each switch mechanism within the housing, the housing may be mounted to a wall or a like supporting surface prior to assembling the operator handle to the housing. An indicator lamp for showing the switch position is mounted in the housing and transparent portions on the actuator and operator handles permit viewing thereof.
