To suppress occurrence of stop in the middle when a slider is slid between stop positions.

In a slider, a plurality of bus bars 3 (a first fixed terminal 32, a second fixed terminal 34, and a third fixed terminal 36) connected with a switch terminal are arranged at a set interval along a sliding direction of a slider 5 which holds the switch terminal (contact) 4, and by sliding the slider between a plurality of stop positions (a DOOR position and an ON position) at which a connection state of the switch terminal and the bus bar is different from each other, the stop position of the slider is switched. A leaf spring 6 for holding the slider at the stop position is provided, and the leaf spring includes a peak part 63 and inclined parts (a first inclined part 64 and a second inclined part 65) gradually lowered to both sides of the sliding direction of the slider with the peak part as a boundary, and, at the inclined parts, imparts pressurizing force to the slider in the sliding direction of the slider and the connecting direction of the switch terminal with the bus bar.
