An operation device includes at least one operation knob on which at least one detection area is set, a contact detection unit to detect contact of a user with the at least one detection area, an operation detection unit to detect an operation performed on the at least one operation knob, and a control unit that controls a controlled object by a combination of a detection area in which contact has been detected and an operation performed on an operation knob including the detection area, and when a predetermined operation on the operation knob is detected while contact remains undetected, the control unit selects a control related to the operation knob from the combination and controls the controlled object.

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 power switching device, an electric energy storage system and an electric tool system are provided. The power switching device includes a plug connected to a power supply device and including an output terminal; and a power switching assembly connected to the plug and including a power switching member, the switching member is used for switching a coupling form of the plug. The power switching assembly further includes a control member for controlling the power switching assembly to move between different switching positions. The control member includes a switching button, and the switching position of the power switching assembly is switched by pressing the switching button.

An input device has a first electrode, a second electrode, and a third electrode. The second electrode opposes to the first electrode while being spaced apart therefrom. The third electrode is spaced apart from the first electrode and rotatably or slidably provided relative to the second electrode. By the third electrode being brought into contact with or spaced apart from the second electrode, an electrical state between the first electrode and the second electrode changes. Based on this electrical change, a rotary manipulation or a slide manipulation is detected.

A computer device including an integrated input device is provided. The integrated input device includes a positive disconnect system including a display of an open connection to the integrated input device when the integrated input device is deactivated. The open connection comprises a visible metal trace on a line coupling the integrated input device to the computer device.

An isolating ground switch includes an enclosure with a frontal surface. A slide channel opens through the top of the enclosure. A conductive switch plate is received in the channel and is bi-directionally slidably positionable between the first position and the second position. A plurality of terminal studs project forwardly from the frontal surface of the enclosure and rearwardly conductively communicate with a conductive portion. When the switch plate is in the first position, the conductive portion engages the switch plate. When the switch plate is in the second position, the conductive portion is isolated from the switch plate.

A motor is generally described. The motor may include an armature and a coil. The coil and armature operatively receive power from a power source. The power induces magnetic fields in the coil and armature to drive the armature. When power is removed, the coils reverse polarity to inductively decelerate the armature.
