PROBLEM TO BE SOLVED: To reduce the power consumption of a contactor used for a high voltage circuit.SOLUTION: A moving contact piece 14 is supported by a shaft 1602, and the shaft 1602 is moved between a contact position contacting with a fixed contact piece and a separating portion separated from the fixed contact piece, with force generated by an actuator 1803. When the shaft 1602 is moved to the contact position, the input of the actuator 1803 is reduced by an input reducing mechanism 22. A force amplifying mechanism 20 is configured to amplify the force generated by the actuator 1803 while the input to the actuator 1803 is reduced by the input reducing mechanism 22, and the shaft 1602 is held at the contact position with the force of the actuator 1803 which is amplified by the force amplifying mechanism 20.SELECTED DRAWING: Figure 1 |
