Abstract: Disclosed is a plug-type connection having a plug and a socket with a plug-in opening for the plug. The socket includes a socket housing and at least one retaining element connected to the socket housing and movable about a first pivot axis. The retaining element secures the plug plugged into the plug-in opening against slipping out of the plug-in opening. A means is provided to displace the retaining element about the first pivot axis out of the position securing the plug against slipping out, thereby releasing the plug, if a specific force acting on the plug opposite to the plug-in direction is exceeded.

Abstract: Disclosed is an electrical contactor, comprising main contacts and secondary contacts, an armature provided for actuating the main contact bridges and secondary contact bridges, and means for restoring the armature from an intermediate position or end position to an initial position, wherein a precharging coil and a pick-up coil are provided in order to electromagnetically drive the armature. A coil yoke is arranged in such a way that the magnetic force acting on the armature due to the magnetic field produced by the precharging coil is greater in the end position of the armature than in the intermediate position when equal current is provided to the precharging coil, wherein said magnetic force corresponds to the restoring force of the means for restoring the armature to the initial position in the intermediate position of the armature and is greater than the restoring force in the end position of the armature.
