A switch (1) includes an insulative case (2), fixed electrodes (3,4) and a movable electrode (5). The case includes a first surface (2c) configured to contact with a circuit board and a second surface (2f) configured to oppose to the circuit board via a gap. The fixed electrodes are accommodated in the case. The movable electrode is accommodated in the case, and is movable 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 (3a,4a) which contacts with the movable electrode and an external connecting terminal (3b,4b) which is exposed on the second surface and is soldered to a land of a wiring terminal provided on the circuit board. The external connecting terminal (3,4) includes a first portion (3a,3b) opposes to the land and a second portion (3d,4d) connected to the first portion and having an area larger than an area of the first portion. |
