PROBLEM TO BE SOLVED: To provide a power switch assembly improved for a capacitive load. SOLUTION: The power switch assembly for the capacitive load 10 which includes a common electrode 14 and first and second discrete electrodes 16, 18, includes a node n1 connected to a voltage source Vcc for receiving power therefrom, a first switching device connected between the node n1 and ground, a second switching device connected between the node n1 and ground, and a driving circuit connected between the node and ground. The driving circuit includes an output terminal connected to the common electrode 14 of the capacitive load. The first switching device is constituted to couple to the first electrode 16 of the capacitive load and to control movement of the capacitive load 10 in a first direction. The second switching device is constituted to couple to the second electrode 18 of the capacitive load and to control movement of the capacitive load 10 in a second direction opposite to the first direction.
