Abstract (en)
Provided is a movable plate 60 which needs less energy consumption, less components, and less assembling processes, but ensures a high productivity. The movable contact plate, comprising three stacked conductive thin plate springs 61, 65, 67, has one end connected to a movable contact terminal 54 and the other end supporting movable contacts 56, 57 integrally fixed thereto. The plate is drivingly moved in its thicknesswise direction by an engagement at a distal end thereof with a card 40 to make and break contacts with stationary contacts 52, 53. The inward conductive thin plate spring has at its distal end a driving elastic tongue 64a and the outward conductive thin plate spring has at its distal end a pair of returning elastic tongues 67b, 67c which are configured to take a condition that only one of the returning elastic tongues makes a contact with the card while the movable contact plate is being moved toward a condition where the movable and stationary contacts are disconnected.
