Quickly closing switch element

A switch for quickly establishing a ground connection for a switching installation, the switch comprising:

• a fixed contact including a first cable feed;
• a moving contact;
• a contact guide including a second cable feed, wherein in an opened state, an insulating clearance exists between the fixed contact and the moving contact, the insulating clearance being at least partially filled with insulating liquid;
• a mechanical energy store;
• a triggering device;
• and
• a locking mechanism, including at least a locking cage, a locking device, and a locking imparter, the locking imparter being connectable to the moving contact and the mechanical energy store being connectable to the locking imparter,
• and wherein:
• the locking imparter is configured to be held in the locking cage via the locking device, and is releasable by the locking device from the locking cage, via the triggering device,
• the moving contact is configured to be accelerated by the mechanical energy store, via the locking imparter, such that the moving contact is configured to be brought into electrical contact with the fixed contact,
• the contact guide is configured to guide movement of the moving contact and contact the moving contact,
• the insulating liquid is displaceable by the moving contact during the closing of the grounding switch
• the locking imparter includes a tension rod and a tensioning nut,
• the locking device is formed by locking balls,
• the mechanical energy store is realized by a spring assembly, and
• the triggering device is formed by a triggering magnet.
