A manually operated device for use with an electrical switching device, the manually operated device having a turning handle indicating a given switching position of the switching device and operatively connected to a driving axle of a rotary drive. A base plate mounted on the rotary drive has a circular rim. To assure unambiguous grip positions in varying installation positions of the switching device, the base plate can be mounted in different offset positions around the driving axle. Furthermore, the rim has a first edge segment that protrudes towards the inside of the rim. The turning handle is operatively connected to a drive plate that can be inserted inside the rim. On the drive plate, an annular second edge segment is configured with respect to a set-back edge area. In the OFF position, the two edge segments align with respect to one another so as to form a complete circular ring, without overlapping. In each position deviating from the OFF position, the second edge segment overlaps or grasps from behind the first edge segment.

Examples described herein relate to circuit breaker assemblies with changeable orientation. In one example, an apparatus includes a circuit breaker assembly and a circuit breaker housing to receive the circuit breaker assembly. The circuit breaker assembly includes a circuit breaker including a contact, a cover plate attached to a surface of the circuit breaker, and a handle movable between a first position and a second position. The circuit breaker assembly is removably attachable to the circuit breaker housing to change an orientation of the circuit breaker assembly.

An electric switching system comprises first, second, and third input terminals, first, second, and third output terminals, an electric switching module, and a control module. The electric switching module includes two first switches and two second switches, each switch having a fixed input contact, a fixed output contact, and a mobile contact. Fixed input contacts are connected to fixed output contacts via mobile contacts in a closed position and insulated from each other in an open position. A holder member is configured to be moved by an electric driving device between a first position and a second position. The holder member includes a first mechanical coupling element and a second mechanical coupling element. The control module includes the driving device. The holder member is mechanically coupled to the driving device via the first coupling element in a primary configuration or via the second coupling element in a secondary configuration.

A switch device for vehicle use is provided with a switch case fixed to a handle bar of a vehicle. A unit case attached to the switch case is capable of rotating with respect to the switch case. An operation lever arranged in the unit case is capable of rotating together with the unit case. The operation lever is capable of operating a predetermined electrical component. The unit case can be freely rotated over a plurality of positions of use at which the operation lever can operate a predetermined electrical component. An object to be operated by the operation lever is made to be different according to a stopping position of the unit case.

A position sensor for sensing the position of a moving part capable of actuating a plunger belonging to the sensor and more specifically a mechanism for orienting the plunger of the sensor. The sensor includes a guide that is rotationally orientable in a body about a first axis XX′ of rotation, and a plunger sliding without rotation in the guide along the axis XX′. A locator prevents rotation of the guide in the body about the axis of rotation, in a given angular position. The locator is fixed nonremovably in the body and possesses either several tabs spaced regularly about the guide and capable of fitting into one position groove to immobilize the guide or several position grooves in which one tab can fit to immobilize the guide. Such a position sensor may find particular application in detecting the positions of moving mechanical components.

A safety switch includes a switch housing which accommodates a switch as well as mechanical and electrical and electronic components, and a head portion securable to an end face of the switch housing in several predetermined angular positions and accommodating a mechanical switching element e.g. a switching wheel which is operated by an actuator. A rigid positioning element is detachably secured to the switch housing and formed with a safety member, whereby the positioning element is adjustable between a locked position in which the safety member is positively engaged in the head portion and an idle position in which the safety member is disengaged from the head portion for allowing a rotation and re-positioning of the head portion relative to the switch housing.

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.

Switches for a variety of circuits for different purposes are formed by using similarly designed contact modules each having a module case incorporating a normally closed or normally open contact mechanism and a plunger for operating this contact mechanism, a single actuator having two end parts and being biased so as to rotate around a supporting axis between these contact modules, this actuator undergoing a rotary motion if a force is applied to one of its end parts so as to operate the plunger of an associated one of the contact modules with at least one of the end parts, a switch case that contains the contact modules and the actuator, and a push button for applying a force on one of the end parts of the actuator from outside the switch case.
