An apparatus (10) controls electrical energy for energizing power utilization devices (14, 16). A control member (28) has a knob (30) for manual engagement and a stem (34) extending along an axis (32). The stem (34) extends into a housing (46) which houses a rotary assembly (84) and a slider member (128). The rotary assembly (84) has a detent plunger (112) biased to engage notches (40, 42) on the stem (34) and which holds the control member (28) in first and second positions along the axis (32). The stem (34) has a tip (36) engaged by the slider member (128) and the slider member moves linearly, orthogonal to the axis (32) during movement of the control member (28) along the axis. An electrical circuit that includes a power source (12) and one power utilization device (14) is completed during movement of the control member (28) along the axis (32) from an initial position. The stem (34) and the rotary assembly (84) have portions (38, 98) which fix the rotary assembly to rotate about the axis (32) with the control member (28). An electrical circuit that includes the power source (12) and another power utilization device (16) is completed during rotation of the control member (28) and the rotary assembly (84) from the initial position.
