A terminal connection portion (22) of a connection terminal (21) has a rectangular hollow member defined by a bottom plate (24), side plates (25, 26) rising from the bottom plate (24), and horizontal ceiling plates (27, 28) connected to these side plates (25, 26). A movable contact plate (29) having a contact portion (29a) thereof facing the ceiling plate (27) is disposed inside the terminal connection portion (22). Stop protuberances (29b, 29c) disposed at the front part of the movable contact plate (29) are anchored by a wing portion (30b) of a support plate (30), and stop protuberances (29d, 29e) disposed at the front edge portion of the movable contact plate (29) are anchored to the front edge portion of the side plates (25, 26).
