A push switch is configured to be mounted on an upper surface of a circuit board the circuit board having a land provided on the upper surface thereof and a side edge. The push switch includes a front section and a rear section. The front section includes a switch contact unit activated by being pushed in a predetermined direction, and is configured to be located outward from the side edge of the circuit board. The rear section includes a terminal connected with the switch contact unit the rear section extending from the front section, and is configured to be disposed on the upper surface of the circuit board. The rear section is connected with the front section, and configures substantially an L-shape in combination with the front section. The terminal is configured to be connected with the land of the circuit board. The predetermined direction is parallel to the upper surface of the circuit board. The gravity center of the push switch is located away from the front section in a direction in which the rear section extends from the front section.
