ABSTRACT:
A switch for controlling the current to a load combining an ON-OFF switch in series with a variable resistor. Switch has a housing which includes an actuator guided along a dimension of the housing. An opening through the actuator permits a portion of the regulator switch to pass through the actuator for operation. The actuator also includes a cam surface for operating the ON-OFF switch.
