RELAY

A relay (100) includes: a cavity (11) is defined in a housing (1). A number of stationary contacts (12) are arranged on the housing (1) at intervals and at least partially arranged in the cavity (11). A drive shaft (2) is movable relative to the housing (1) in an axial direction of the drive shaft (2), and an axial end is provided with a support piece (21) at least partially inserted into the cavity (11). A moving contact assembly (3) is matched with the support piece (21) through a sliding structure, so that the moving contact assembly (3) is movable relative to the support piece (21) between a first position contacting the stationary contact (12) and a second position away from the stationary contact (12). An elastic member (5) is arranged between the moving contact assembly (3) and the support piece (21) to apply an elastic force to the moving contact assembly (3) to move toward the first position.
