In the seat switch, within a case main body 11, there are arranged a vertical switch portion 16, a seat slide switch portion 15, and a vertical switch portion 14 in this order. To slide a power seat in an X direction, a seat switch knob 24 is operated in the X direction. In response to this, a seat slide operation shaft 22 is moved in the X direction, so that a projection 33a provided on an operation body 33 is pressed against one side (X-direction side) of a movable contact disposed in each opening and closing portion to thereby move the movable contact. As a result, the X-direction side contact end of the movable contact is contacted with a fixed contact. Due to this, a seat sliding motor connected to the switch portion 14 is driven or rotated forward and, because of the forward rotation of the motor, the power seat is moved forward in the X direction.
