A connection apparatus for connecting electrical devices, in particular electric motors to an AC system, has a housing which has at least one housing portion. A plurality of first and second conductor terminals are arranged in the at least one housing portion. Each conductor terminal has at least one or two or more individual terminals and a configuration plug. The configuration plug electrically connects individual or a plurality of the first and/or second conductor terminals in at least two different positions in order to obtain at least two different circuit types. The configuration plug is rotatably or slidably guided in or on the housing or at least on the at least one housing portion. Due to this relative movement, plug can be rotated and/or displaced into at least two different positions, in order to provide the at least two different circuit types.

A disconnecting switchgear has three mutually exclusive positions II-0-I, with position II energizing the load circuit, position 0 de-energizing the load circuit and position I grounding the circuit, which reduces the electrical risk when interacting with an electrical panel. The switchgear includes a control interconnected with a body, where the control includes a gripping mechanism with an electrical labelling element, an extension mechanism, a locking mechanism and indicator labels; the body includes a group of external electrical conductors or connection terminals, a group of internal electrical conductors or poles, an earth short-circuit electrical conductor, displays of electrical quantities, luminous indicators, and sight glasses for viewing moving poles; electrical conductors and electrical contacts interconnected with a drive shaft and the latter to a power-transmission mechanism.

In one example, a rotary knob switch includes: a knob head; a fixing mount disposed below the knob head and configured to allow at least a portion of the bottom of the knob head to pass through it; cam located at the bottom of the fixing mount and to be mated with the bottom of the knob head, a side of the cam forming at least one protruding control curved surface; and a slider, said slider being coaxial with the cam, ramp with different heights being provided along edge of the slider, wherein, when the cam rotates, the control curved surface of the cam presses the ramp of the slider, such that the slider slides along axial direction towards the bottom of the rotary knob switch, the knob head comprises an indicator block, the lower part of the indicator block is provided with an axial light guide column.

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.

The electrical switch includes three fixed contacts and a rotatable knife contact being connected with a permanent electrical connection to a third one of the fixed contacts and including at least one pair of longitudinal blades. The rotatable knife contact connects in a first switching position only a first one and a third one of the fixed contacts electrically together, and in a second switching position only a second one and a third one of the fixed contacts. The rotatable knife contact connects further in a zero switching position the first, the second and the third fixed contact electrically together.

An input apparatus for a vehicle includes: a housing mounted on the vehicle; a substrate disposed inside the housing; a push button device disposed in the housing to be pressed; a dial device arranged and configured to be rotated about the push button device, being non-peristaltic when the push button device is pressed, and maintained in a posture with respect to the housing, a first sensing device disposed on the substrate to sense pressing of the push button device; and a second sensing device disposed on the substrate to sense rotation of the dial device.

Various examples of park brake interface modules which are utilized as human machine interfaces (HMI) in vehicles are provided. In one example, a park brake interface module for a vehicle includes an actuation member mounted to an electromechanical switch to actuate the park brake. The actuation member includes a finger pad opposite the front surface and the actuation member is movable between a brake apply position and a brake release position to actuate the vehicle park brake. In another example, the actuation member is pivotally mounted to the electromechanical switch device and the actuation member is pivotable between the brake apply position and the brake release positions to actuate the park brake.

A switch device includes, a movable terminal including a snap action mechanism that bends a spring when a user moves an operating portion, a first fixed terminal that contacts the movable terminal when the spring is not bent, a second fixed terminal that contacts the movable terminal when the operating portion is moved by a specified amount to bend the spring, a case including an opening, and a cover that closes the opening and is separate from the first fixed terminal. When the opening is closed by the cover, the first fixed terminal is positioned in the case by the cover.
