The contactor is a normally-open high current contactor.

The compliant contactor can be either a single pole compliant contactor (50) or double pole compliant contactor (72).

The transition auxillary contactor operably controls the operation of a shorting contactor, and the shorting auxillary operatively controls the operation of the run contactor.

A switch position indicia is exposed when the operator is withdrawn.

The contact bridge (SW1) of contactor provides trigger signals when the contactor is disconnected.

A precharging contactor is controlled to charge the input filter capacitor prior to closing the main contactor to further protect the contacts of the main contactor.

According to different control voltages, it can be divided into DC contactor and AC contactor.

The main contactor and the precharging contactor, in the same way as the precharging resistor, are arranged in the housing.

The invention relates to a contactor detector (100), which can be arranged into a functional relationship with a contactor, which contactor detector comprises detecting means for detecting the failed contactor.

The drive circuitry includes a switching regulator having a switch and an inductive element coupled between the switch and the lower voltage node to electrically connect the switch to the lower voltage node.

The impedance contactor closes before the power contactor on the closing stroke to introduce the charging impedance into the circuit.

A through hole is formed on the contactor.

The switch can be normally open or closed.

The contactor further includes a keeping portion.
