When a mechanical block manoeuvre actioned by a key is required in order to start the interlocking sequence, it is advised to use an cylinder interlock.

The key is trapped if turned at 90º. Turning the key at 0º position, it is released and the contacts are inverted.

The interlock cylinder, as every item in our catalogue, is completely compatible with the rest of our articles. As the same key format can be used, it could be utilized in any interlocking sequence even if it is composed by more items.
