Key exchange boxes are used to release one or several keys by introducing one or more keys which are then trapped inside the box.

For example, all keys from earthing switches are trapped inside the box in order to release keys giving access to the transformer.

The minimum number of cylinders is 2. The maximum depends on the space available to install the lock. In some cases, depending on the number of keys to be used and the space available, several boxes have to be used as a “chain”. The last key of the preceding box becomes the first key of the following box and so on.

The switch at either end of the box to give an electrical signal showing whether the key is inside the lock or not.
