Abstract
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.
Claims20
An apparatus comprising:
- an electrical pole unit including an actuating shaft that reaches through the pole unit along a switch axis and is rotatable about the switch axis to switch the pole unit between open and closed conditions;
- wherein the actuating shaft has an end portion, the end portion defines a cavity that is centered on the switch axis, and the cavity is configured for receiving a hub on an end portion of another actuating shaft in rotation-transmitting engagement;
- and
- the actuating shaft further has an opposite end portion defining a hub that is centered on the switch axis and configured for fitting within a cavity in another actuating shaft in rotation-transmitting engagement;
- whereby the actuating shaft is configured to mate coaxially with another actuating shaft in another pole unit in rotation-transmitting engagement at locations centered on the switch axis.
2 more elements
An apparatus comprising:
- a first electrical pole unit including a first actuator shaft that is rotatable about a switch axis to switch the first electrical pole unit between open and closed conditions;
- and
- a second electrical pole unit including a second actuator shaft that is rotatable about a switch axis to switch the second electrical pole unit between open and closed conditions;
- wherein each of the first and second actuating shafts has an end portion defining a cavity that is centered on the switch axis, and each cavity is configured for receiving a hub on an end portion of another actuator shaft in rotation-transmitting engagement;
- and
- wherein each of the first and second actuator shafts further has an opposite end portion defining a hub that is centered on the switch, and each hub is configured for fitting within a cavity in another actuator shaft in rotation-transmitting engagement;
- whereby the actuator shafts are configured to mate coaxially in rotation-transmitting engagement at locations centered on the switch axis.

An apparatus comprising:
- a first electrical pole unit including a first actuator shaft that is rotatable about a switch axis to switch the first electrical pole unit between open and closed conditions;
- and
- a second electrical pole unit including a second actuator shaft that is rotatable about a switch axis to switch the second electrical pole unit between open and closed conditions;
- wherein each of the first and second actuator shafts as an end portion defining a cavity that is centered on the switch axis, and each cavity is configured for receiving a hub on an end portion of another actuator shaft in rotation-transmitting engagement;
- wherein each of the first and second actuator shafts further has an opposite end portion defining a hub that is centered on the switch axis, and each hub is configured for fitting within a cavity in another actuator shaft in rotation-transmitting engagement;
- and
- the hub on the first actuator shaft is received within the socket on the second actuator shaft;
- whereby the actuator shafts are mated coaxially in rotation-transmitting engagement at locations centered on the switch axis.
