Abstract (en)

A switch system with bypass contact, which includes a stationary contact and a movable contact; the stationary contact is connected to a power supply; the movable contact is connected to a load; the movable contact is movable between an open position and a closed position; upon being in the open position, the movable contact is not in contact with the stationary contact; upon being in the closed position, the movable contact is in contact with the stationary contact; a bypass contact is arranged on the stationary contact; a parallel circuit is formed upon the movable contact being in contact with the stationary contact and the bypass contact being in contact with the movable contact; the power supply supplies power to the load through the parallel circuit; the parallel circuit includes a circuit that the power supply is electrically connected with the load through the stationary contact and the movable contact in turn; and the parallel circuit further includes a circuit that the power supply is electrically connected with the load through the stationary contact, the bypass contact, the movable contact in turn.
