A test system and method for relay connection and testing of a power transmission and distribution grid including a fixed connection block connected to the power transmission and distribution grid, and a mobile plug which connects the fixed connection block or a mobile test block with the relay when the mobile plug is inserted into the fixed connection block or the mobile test block. The mobile test block provides a connection to an external relay testing device when the mobile test plug is inserted into the mobile test block, the fixed connection block provides internal shorting that is activated when the mobile plug is not inserted into the fixed connection block and is deactivated when the mobile plug is inserted into the fixed connection block, and the fixed connection block, mobile plug, and the mobile test block provides an interaction between a power transmission and distribution grid side and a relay side. This allows a quick recovery when relays are damaged in a cyber-attack.

A device and a method for integrating at least one electrical element into an electrical circuit during ongoing operation of the electrical circuit. In addition, a meta module for dynamic extension of an electrical circuit is possible to add any desired number of electrical elements.

Switchable grounded terminal loads are built into, or otherwise coupled to, connectors on motherboards and control devices. The terminal loads are coupled to the bus termination at the connector when the connector is stuffed (connected to a mating connector). The switchable grounded terminal loads replace dummy connectors in preventing empty unstuffed connectors from increasing error risks on active channels.

The invention relates to an electrical plug connector for a safety restraint system, preferably for an airbag ignition system, including at least two contact terminals disposed within the plug connector and a shorting clip, that is configured to short circuit the at least two contact terminals in an uncoupled or incorrectly coupled condition of the plug connector. The shorting clip includes at least two shorting tongues. Each shorting tongue is electrically connected with a respective contact terminal. Each shorting tongue further includes at least one electrical contact surface and at least one of the shorting tongues includes an actuating member. The actuating member is provided with an actuating surface that is configured to interact with a separator device. The contact surfaces are not arranged within the same plane as the actuating surface(s).
