Abstract: A system for controlling power to an electrical load includes a linear slide dimmer and a switch, whose pushbutton actuator moves up and down with the dimmer slider. When the pushbutton is depressed, to actuate the switch, it rides in and out in the slider. The slider only moves up and down. In one embodiment, a light is visible through the pushbutton in a darkened environment. In another embodiment, a wallbox-mountable switch assembly includes a pushbutton-actuated, alternate-action mechanical power switch whose pushbutton, when depressed, moves within a bezel that is attached to the switch support.
