If there is more than one power wire, connect them together with a pigtail before installing the pigtail on the switch. Connect the black wire from the cable to the device being switched to the other screw on the switch, and screw the switch to the box.

Color the white wire with a black tape, and attach it to the other screw on the switch. Connect grounds, in the device, together before connecting the white wire in the cable going to the switch box.
