Abstract
A varying signal, which may be a feedback signal, is combined with a control signal to control the actuators (117 and 119) of a switch. The method compensates for varying temperature conditions as well as variations in the manufacturing process of the actuators (117 and 119) and a member (101) of the switch that is attached to the actuators (117 and 119), which member (101) changes positions to change the state of the switch. The varying signal, in combination with the control signal, determines a pulse width, during which time energy is applied to the actuators (117 and 119).
