An input device includes: a rotating member that rotates about a predetermined rotation axis; and a mover that includes a protrusion protruding toward an inner peripheral surface of the rotating member and moves in a direction different from a rotation direction of the rotating member along with rotation of the rotating member. The protrusion protrudes toward an inner peripheral surface of the rotating member. The rotating member includes a first projection and a second projection that project from the inner peripheral surface toward the mover. The protrusion of the mover is inclined with respect to the predetermined rotation axis and disposed between the first projection and the second projection.

A rotor system for a multi-pole rotary electrical switch having a rotor with a top and a bottom. Bus plate connectors are held in chambers on the bottom of the rotor. Retainers in the chambers, engaging only sides of the bus plate connectors, prevent the bus plate connectors from dropping out of the chambers when the bus plate connectors are placed above bus plates in a bus plate holder to place the switch in an “OFF” position. Support members extend from a side of the rotor to support the bus plate connectors above the bus plates. When the rotor is rotated to the “OFF” position the support members are rotated up onto support posts positioned in the bus plate holder. When the rotor is rotated to an “ON” position the support members are rotated off the support posts and the bus plate connectors are pressed down against the bus plates by a spring, thereby creating electrical connections between the bus plate connectors and the bus plates.

A switch, a power conversion apparatus, and a power supply system. The power supply system includes a control unit, a switch, a direct current source, and a power conversion unit. The switch is electrically connected between the direct current source and the power conversion unit, and the control unit is configured to send a switch-off signal to the switch when a fault occurs on the direct current source or the power conversion unit. The switch includes a contact component, a trip-free structure, and a knob that are sequentially disposed in a stacked manner in a first direction. A trip unit of the trip-free structure is configured to receive the switch-off signal, to unlock the trip unit from the cradle. The cradle drives the connecting rod structure to move, to separate the moving contact from the fixed contact.

A switch apparatus, includes: a base module including a base case, and a moving magnet movably mounted in the base case; and a manipulation module including a manipulation case, and a first magnet fixedly mounted in the manipulation case, wherein the moving magnet moves between a hold position and a releasable position, the hold position refers to a position in which the manipulation module is held onto the base module as an attractive force acts between the moving magnet and the first magnet, and the releasable position refers to a position in which the manipulation module is releasable from the base module as a repulsive force acts between the moving magnet and the first magnet.

A circuit breaker system includes an internal operating handle disposed inside an enclosure and coupled to a shaft extending from a circuit breaker. The internal operating handle includes a dog clutch coupled to the shaft and a rotary handle coupled to the dog clutch. The rotary handle is operative to rotate the shaft when the dog clutch is engaged. A safety operating handle system for turning a shaft to operate a circuit breaker includes a rotary handle and a dog clutch having a first clutch member coupled to the rotary handle and having a second clutch member coupled to the shaft. The dog clutch is operative to transmit a rotation of the rotary handle to the shaft when the first clutch member is in an engagement position.

A switch and methods of assembling a switch. The switch may include a housing; a first terminal electrically coupled to a power source; a second terminal electrically coupled to a load; a contact having a first contact end and a second contact end, the contact being operable to be in a closed position, in which the first contact end engages the first terminal and the second contact end engages the second terminal such that the contact electrically connects the first terminal to the second terminal, and an open position, in which the contact does not electrically connect the first terminal and the second terminal; and a biasing member configured to bias the contact towards the first terminal and the second terminal, the biasing member being operable to apply a first biasing force proximate the first contact end and a second biasing force proximate the second connect end.
