To provide a switch that achieves sure electrical contact/separation by a simple configuration regarding a switch mainly used for on/off control or the like of a vehicle stop lamp.
A plurality of recessed parts 12B are provided at least at one end part of a fixed contact 12, implanted to the inner wall of an almost-box-like case 1 or at one end of a movable contact 14 that is held by an operating body 3 and whose end part is elastically in contact with the fixed contact 12. Consequently, even if minute carbide and wear powder or the like are generated due to progress of burnout and wear of the fixed contact 12 and the movable contact 14 caused by repetitive operation of a switch 20 for a long period of time, the minute carbide and wear powder accumulate in the plurality of recessed parts 12B so as to prevent them from adhering to the contact surface. Therefore, a stable contact between the fixed contact 12 and the movable contact 14 is achieved, so that a switch is obtained that achieves sure electrical contact/separation.
