A dimmer switch includes a housing having a frame having a single actuator opening therethrough. The opening has first and second portions. A controllably conductive device is disposed in the housing for adjustably controlling electrical power to a load. A pivotable toggle actuator is accessible through the first portion of the single actuator opening and pivotable between a first and second positions by a user. A slidable dimmer actuator is accessible through the second portion of the single actuator opening. The slidable dimmer actuator is slidable linearly within the second portion of the single actuator opening anywhere between first and second positions by a user. The pivotable toggle actuator is operable for controlling the controllably conductive device to turn on and off power to the load, and the slidable dimmer actuator is operable for controlling the controllably conductive device to adjustably control the level of power to the load.
