A typical application of the Y key exchange box  is machine guarding with more than one access points to the hazardous area.  The key exchange box is used as a part of a safety system, which ensures a machine is shut down, before access to the hazardous area is allowed.

The system involves a KS key switch for the electrical supply and typically more than one AI access interlock for part body access.

The removal of the isolation key from the key switch isolates the electrical supply to the machine.

This key is taken to the Y key exchange box to release the trapped keys. The released keys are used to gain access through the AI door interlocks. The machine cannot be restarted until all keys are returned to the Y key exchange box and the end key (power isolation key) is removed and taken to the KS key switch.
