A movable contact assembly (100) may be moved by a magnetic field of the coil (14a) to be brought into contact with the stationary contact (13) when a current is supplied to the coil (14a), and moved by an elastic force of the return spring (17) to be separated from the stationary contact (13) when a current is cut off from the coil (14a). The movable contact assembly (100) may include a movable contact (110), a shaft (120), and a snap-fit portion (130). The movable contact (110) may be brought into contact with or separated from the stationary contact (13). The shaft (120) may move back and forth through the center of the coil (14a), and may include a shaft body (121), a head (122) formed at an end portion of the shaft body (121), and a pair of rib portions (123) protruded from both sides of the head (122), respectively, and separated from each other to allow the movable contact (110) to be inserted from the upper portion of the head (122) and support both sides of the movable contact (110). The snap-fit portion (130) may include a pair of hooks (131) disposed on the rib portions (123), respectively, to be pushed by the movable contact (110) and deformed to be spaced apart from each other while the movable contact (110) is being inserted between the rib portions (123), and then elastically restored to cross both sides of the movable contact (110) when the movable contact (110) has been inserted between the rib portions (123). |
