摘要:
A switch is constituted by a movable conductive portion and a pair of fixed conductive portions. The fixed conductive portions are arranged on a substrate, and are each constituted by at least one strip member. A first main conductive pattern and a second main conductive pattern are arranged on the substrate in correspondence with the fixed conductive portions. The movable conductive portion electrically shorts the pair of fixed conductive portions upon coming into contact with both of them. The strip members that constitute the fixed conductive portions each have a first end portion and a second end portion in the extending direction, and the end portions are electrically connected to the corresponding main conductive patterns.

A keyboard instrument includes: a detectable portion that is disposed on a movable member that is displaceable in response to a playing operation by a user, a detection board; a control board that is discrete from the detection board; and a wiring portion. The detection board includes a detection coil facing the detectable portion, and a detection circuit that generates a detection signal depending on a distance between the detection coil and the detectable portion. The control board includes a control integrated circuit configured to generate, based on the detection signal, displacement data indicating a position of the movable member. The wiring portion includes a wiring configured to transmit the detection signal from the detection board to the control board.
