[Problem to be solved by the invention] In this type of switching switch, the contact pieces move in a direction across the fixed contact as the movable member is displaced, but in this case, the pair of contact pieces is moved by a spring means. Because it is brought into strong pressure contact with the fixed contact,
When the contact piece moves, the end of the contact piece on the fixed contact side is pulled in the opposite direction to the moving direction. Furthermore, when the movable contact starts contact with the fixed contact, the contact piece rides on the tapered part formed at the end of the fixed contact and tilts.
Unreasonable force will be applied to the support portion of the contact piece. Furthermore, since the direction of movement of the movable contact is changed as appropriate in connection with the tap switching operation, force is applied to the support portion of the contact piece from a different direction each time the direction of movement of the movable contact is changed. .

The force that acts on each contact piece when a pair of contact pieces slide with the fixed contact between them, and the force that acts on each contact piece when contact between the movable contact and the fixed contact starts. This force can be easily received by the inner surface of the guide groove. Therefore, it is possible to prevent excessive force from being applied to the support part of the contact piece, prevent deterioration of the support part and prevent rattling, and prevent poor contact between the movable contact piece and the fixed contact piece. to prevent

Further, since there is no need to add an extra reinforcing member or increase the mechanical strength of the support portion, there is an advantage that the cost of the switching switch can be reduced.

[Claims for Utility Model Registration] A frame fixed to a movable member, a pair of contact pieces arranged to face each other via the frame and supported by the frame, and the pair of contact pieces are brought close to each other. a movable contactor having a spring means for biasing the movable member in the direction; and a plurality of plates arranged side by side in the direction of displacement of the movable member so that when the movable member is displaced, the pairs of contactor pieces sequentially contact each other. a fixed contact, wherein the pair of contact pieces slides into contact with each fixed contact with each fixed contact sandwiched therebetween as the movable member is displaced, The frame has a pair of guide grooves that respectively receive the pair of contact pieces, and each of the pair of contact pieces is loose in the pair of guide grooves with one end of each fixed contact side protruding from the frame. A contact piece supporting pin is provided to loosely pass through the pair of contact pieces and the frame, and spring receivers are fixed to both ends of the pin, and the spring receivers at both ends of the pin and the A switching switch characterized in that springs constituting the spring means are respectively disposed between the pair of contact pieces.
