Switch
A switch includes an insulative case with fixed electrodes and a movable electrode therein. The case includes a first surface configured to contact with a circuit board and a second surface configured to oppose to the circuit board via a gap. The movable electrode moves between a first position for placing the fixed electrodes in a conductive state and a second position for placing the fixed electrodes in a nonconductive state. Each of the fixed electrodes includes a contact terminal which contacts with the movable electrode and an external connecting terminal exposed on the second surface and soldered to a land of a wiring terminal on the circuit board. The external connecting terminal includes a first portion opposed to the land and a second portion connected to the first portion that has an area larger than an area of the first portion.
