Abstract
A switch including a breaker, the size and cost of which can be reduced is provided, the switch including a breaker having a structure such that a mechanical switch for turning an electric circuit on/off includes a breaker for interrupting the electric circuit. Moveable contacts arranged to approach and move apart from fixed contacts are elastically urged in a direction where the moveable contacts move apart from the fixed contacts. When the breaker is set, the moveable contacts are located apart from the fixed contacts in such a manner that a short distance is maintained. By switching the mechanical switch on, a solenoid is operated to bring the moveable contacts into contact with the fixed contacts. When the breaker is operated, the elastic urging force is suspended to move the moveable contacts apart from the fixed contacts for a distance longer than a distance for which the moveable contacts are located apart from the fixed contacts when the mechanical switch is switched off.
