An apparatus includes a circuit interrupting device installed in a cabinet. The circuit interrupting device has an actuator configured for rotation about a switching axis to switch the device between ON and OFF conditions. The apparatus further includes a front access hub supported for rotation about an axis orthogonal to the switching axis. A handle is coupled to the front access hub to rotate the front access hub about the orthogonal axis. A mechanism interconnects the front access hub with the actuator to rotate the actuator in response to rotation of the front access hub.

A switching device including a frame, a roll element, a control shaft, a drive system and a roll spring. The control shaft is adapted to control rotation of the roll element such that rotating the control shaft from an ON-position to an OFF-position carries out an opening event in which the roll element transfers from a first position to a second position. The drive system includes an actuator and an actuator spring. The drive system is adapted to rotate the roll element during the opening event to an intermediate position located between the first position and the second position. The roll spring is connected between the frame and the roll element, and is adapted to rotate the roll element to the second position during the opening event.

A modular electrical switching device (1A) obtained by juxtaposing a control module (10) and a switching module (20), each comprising a mechanism that rotates about a rotation axis (A), coupled together by complementary coupling end pieces (11, 12; 21, 22). The control module (10) is designed to be controlled by a control rod (3) as well by a front control through a front entry opening (30) provided on the front side of the control module (10) as by left or right side control through two side entry openings (34, 35) provided on the sides of the control module (10), respecting a same direction of operation. The coupling end pieces (11, 12) of the control module (10) are provided on separated male (110) and female (120) coupling parts inserted between the modules (10, 20), when they are juxtaposed to form the switching device (1A).

A rotary switch operating apparatus has a drive shaft and a first and a second drive element, the first drive element having a rotationally fixed coupling to the drive shaft, and the second drive element being rotatably mounted on the first drive element. The apparatus includes a spring coupling the first and the second drive element together with a spring action, a lock limiting rotational movements of the second drive element in a first rotation direction and a second rotation direction, opposite the first, and a releaser for canceling rotational movement limitation of the second drive element in pre-specified rotation positions of the first drive element. Latches bearing against the drive elements' guide sections are provided, the first drive element guide section having release sections as releasers and the second drive element guide section having two latch stops as locks.
