A push switch is provided with a knob that causes the movable contact point in contact with the fixed contact point to slide thereon by a push operation of the knob, thereby connecting/disconnecting the movable contact point and the fixed contact point. A sliding direction of the movable contact point is set to a direction vertical to the push direction of the knob, and the push operation of the knob allows the movable contact point in contact with the fixed contact point to slide in a direction vertical to the push direction of the knob.
