Abstract
The utility model provides a direct-current contactor. The contactor comprises a fixing frame, an electromagnet fixed on the fixing frame, a separation plate arranged above the electromagnet, contacts and an auxiliary switch assembly used as a self-locking circuit in an electric control circuit. The electromagnet is wound by a coil. The coil is connected with a wiring terminal which can be connected with a power supply. The contacts are mounted on the separation plate, and include a moving contact and a static contact matching with each other. The wiring terminal and the static contact are fixed on the separation plate. The moving contact and the static contact are covered by a protection sealing shield, so that dust and tiny materials are prevented from dropping on the moving contact and the static contact, and safety faults are reduced.
