Abstract
A push button switch includes a push button, a movable contact that moves together with the push button, and a fixed contact with respect to which the movable contact comes into contact or separates in accordance with the operation of the movable contact. The push button switch includes a light emitting element, and a light receiving element. A light emitting position where light emitted from the light emitting element is radiated to the outside, and a light receiving position where light detected by the light receiving element is received from the outside are disposed outward of an edge of the push button when viewed in a pushing direction. The light receiving element is disposed to detect light emitted from the light emitting element and reflected by an object in a detection region set in a space on the push button side in the opposite direction to the pushing direction.
