PROBLEM TO BE SOLVED: To use a card manufacturable with a metal mold having a sufficient mold strength and a long service life by providing projection parts to make contact with different positions on both sides of a movable contact piece on the opposed inside surfaces of the locking part of a card at least one each. SOLUTION: A pair of projections 44a, 44b for nipping the upper edge 21a of a movable contact piece 21 are provided on the opposed inside surfaces of a locking hole 42a. Each of the projections 44a, 44b makes contact with one halved side of the movable contact piece 21 without opposing each other. Therefore, a space width S can be increased. A card 40 is fitted to a second insulating wall 12, and the upper edge 21a of the movable contact piece 21 is engagingly locked in the locking hole 42a whereby the card 40 is slidably supported. The regulating projection 43 of the card 40 becomes pressure contactable with the upper end of a regulating spring 30. Accordingly, the width dimension of the locking hole or slit of the card can be increased to facilitate the molding of the card.
