A method of operation of a controller and a controller are provided. The controller is configured to receive from a first electrical switch information indicating a state change at the first electrical switch. The controller is configured to determine, based on the received information from the first electrical switch, at least one of one or more electrical switches or one or more electrical outlets. Further, the controller is configured to send to the at least one of the one or more electrical switches or the one or more electrical outlets an action order to change a state pursuant to the information indicating the state change at the first electrical switch. The controller may be configured to receive a programming indicating the at least one of the one or more electrical switches or the one or more electrical outlets that are responsive to the state change at the first electrical switch.

A connector has a first end provided with a first interface and a second end provided with a second interface. The second interface includes a first switch unit and a second switch unit, where the second switch unit is connected to a control terminal of the first switch unit and a ground pin of the second interface, and a preset reference voltage is input into the ground pin of the second interface. In a case that the second interface is disconnected from a to-be-charged device, the first switch unit is in an off state. In a case that the second interface is connected to the to-be-charged device, the ground pin of the second interface is connected to a ground pin of the to-be-charged device, the ground pin of the second interface is grounded, and the first switch unit is in an on state.

Disclosed a device for the load-free disconnection of a plug-in connection, which has an electrical disconnecting device and a locking clip. The locking clip can be pivoted both into a position locking the plug-in connection and into a position unlocking the plug-in connection. The device also has a sensor system, which interacts with the locking clip in its locking position to detect the locked state, in order to control the electrical disconnecting device.

An electrical connector includes a plug that mates with a receptacle. In a medical application, the plug is connected to electrical leads that pass through a patient's skin to an implanted medical device in the patient's body, while the receptacle is connected to external medical equipment. All electrical contacts in the plug are on internal portions. The receptacle includes annular contacts that contact the internal electrical contacts on the plug when the plug and receptacle are properly mated. The receptacle includes a plurality of annular electrical contacts that have a first diameter and are separated by a plurality of annular insulators having a second diameter smaller than the first diameter.

Described is a power connector device for separating an electrical connection under direct current (DC) voltage or alternating current (AC) voltage between an electrical connector element and an electrical contact element. The power connector device includes the electrical contact element. The electrical contact element has a first conductive part and a second conductive part spaced apart one from the other so as not to be directly electrically conductively connected to one another. The power connector device includes a semiconductor switch for maintaining an electrical connection between the electrical connector element and the electrical contact element during separation of contact between said electrical connector element and said first conductive part to thereby prevent arcing during electrical disengagement of the electrical connector element from the electrical contact element. The first conductive part of the electrical contact element is only electrically connected to the second conductive part of the electrical contact element when the semiconductor switch is activated or when the electrical connector element is in contact with both the first and second conductive parts of the electrical contact element.

A plug and socket safety system, wherein a socket element is not energized unless both engaged with the plug element and moved to an energized, locked position, and wherein the plug element cannot be removed from the socket element until the socket element is moved to a neutral, unenergized, unlocked position.
