Abstract
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.
