PURPOSE:To make it possible to set a rotating speed of uniformed quality, by driving a mechanical governor switch from outside in a simple substance of an armature and by setting a fixed contact and movable contact in a specified contacting state. CONSTITUTION:In composition a mechanical governor switch for a micromotor is equipped with an armature 10 to set a rotating speed and a motor 11 to drive it at specified rotating speed from outside with high accuracy. On the base 3 of this armature 10 a movable contact 1 and a fixed contact 4 to set are provided and a brush 13 to detect the contacting state between the both contacts 1 and 4. Being driven from outside in a simple substance of an armature and setting the fixed contact 4 and the movable contact 1 in a specified contacting state, the mechanical governor switch sets its speed control state in motor rotation. As a result, the setting work can easily be automated and the manhours required for setting work reduced. |
