Title:
OPERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/125631
Kind Code:
A1
Abstract:
An unexpected load is prevented from being generated between a switch (1) body and an operating device (2) and a power transmission mechanism (3) is prevented from being damaged to match the opening/closing state of the operating device (2) and the opening/closing state of the switch (1) body. A torque limiter (10) is mounted between a motor (7) and a reduction gear mechanism (11) in the operating device (2). Further, after the completion of the opening/closing operation, the circuit configuration of a motor control circuit (8) is switched over into a circuit configuration in which a braking current flows through resistances (R1, R2), so that the torque generated by the motor (7) is reduced, thereby reducing the applied load on the power transmission mechanism (3).
