Abstract (en)
[origin: EP2426686A1] To prevent generation of an unexpected load between a main body of a switch 1 and an operating device 2, to prevent breakage of a power transmission mechanism 3, and to match an open/close state of the operating device 2 with an open/close state of the main body of the switch 1. A torque limiter 10 is provided between a motor 7 and a speed reduction mechanism 11 in the operating device 2. Further, the operating device has a circuit configuration such that, after completing an open/close operation, a circuit configuration of a motor control circuit 8 is switched, and a braking current flows to resistors R1 and R2. By reducing a torque generated by the motor 7, an application load to the power transmission mechanism 3 is reduced.
