Abstract (en)

[origin: EP2189995A2] The controller has a gear motor (2) for operating a double latching mechanism (3), and a transmission chain (4) to transmit an output torque of the motor to an element (30) of the mechanism. An opening spring (35) and a closing spring (34) are compressed simultaneously by a single manual operation in an interrupted state of the chain through an output torque along two different directions. The chain and the mechanism allow the opening spring to remain in a compressed state during compression of the closing spring, in the uninterrupted state. An independent claim is also included for a method for operating a double-latching mechanism with two spiral springs, of a high or medium voltage electrical equipment controller.
