A high current switching device includes an electrical switch assembly and an input shaft operatively connected to the electrical switch assembly. An actuator assembly is attached to the input shaft and is configured to move the input shaft to operate the electrical switch assembly. The actuator assembly includes a mechanical advantage device operatively attached to the input shaft. An actuator is coupled to the mechanical advantage device such that movement of the actuator causes movement of the input shaft to operate the electrical switch assembly. The mechanical advantage device is configured to decrease an amount of force required to move the input shaft by the actuator.

Switching assembly with mechanical advantage device

Switching device

A electrical pole unit includes an actuator shaft that is rotatable about a switch axis to switch the pole unit between open and closed conditions. The actuator shaft is configured to mate coaxially with another actuator shaft in another pole unit to transmit rotation from one actuator shaft to another without a fastener to interconnect the shafts.

Actuating shaft structure for an electrical switch

An apparatus includes a switch having alternately open and closed conditions, and a shunt trip mechanism configured to detect and respond to an electrical fault condition. The apparatus further includes an operating mechanism including a spring assembly. The operating mechanism is actuatable manually to deflect the spring assembly into a stressed condition, and is actuatable automatically in response to the shunt trip mechanism to shift the switch into the open condition upon return deflection of the spring assembly from the stressed condition. The spring assembly may include springs connected in parallel.

Electrical switching apparatus with springs and shunt trip mechanism

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.

Safety switch access arrangement

An electrical switch assembly includes a first contact supported for movement into and out of electrical connection with a second contact. A cam assembly is configured to deflect a spring into a stressed condition, and to move the first contact into electrical connection with the second contact under a bias of the spring upon return deflection of the spring from the stressed condition. A motor has an output member. A linkage interconnects the output member with the cam assembly to deflect the spring into the stressed condition in response to movement of the output member.
