摘要： A switch assembly adapted and a method for switching power to a circuit having a power source. The switch assembly includes current carrying contacts and a coupling member. The coupling member has conductive pads for engaging the current carrying contacts and a contact bridge extending between the conductive pads. An actuator assembly moves the coupling member between a closed position in which the conductive pads of the coupling member engage the current carrying contacts and an open position in which the conductive pads of the coupling member are disengaged from the current carrying contacts. Opposing electromagnetic forces are generated between the contact bridge and the conductive pads to resist electromagnetic repulsion forces generated between the current carrying contacts and the conductive pads as the actuator assembly approaches or is in the closed position.

摘要： A pre-charge circuit (10) is provided for an electromechanical relay (12) having a coil (22) and relay contacts (26). The pre-charge circuit (10) includes a semiconductor switch (30) configured to be electrically connected across the relay contacts of the electromechanical relay. The pre-charge circuit includes a resistor (32) configured to be electrically connected in series with the semiconductor switch between the coil and the relay contacts of the electromechanical relay. The pre-charge circuit includes a driver (34) configured to be electrically connected between the coil of the electromechanical relay and the semiconductor switch such that the driver is configured to power operation of the semiconductor switch. The semiconductor switch is configured to pre-charge a capacitor (16) of a load (14) of the electromechanical relay with electrical current through the resistor for limiting in-rush electrical current supplied to the relay contacts of the electromechanical relay.
