A key exchange box (KEB) is used when any number of keys need to release any other numbers of keys. For example, when a single key from a switch needs to release 5 keys to go to several hatches the key exchange box makes this exchange: the key from the switch is inserted, only after which any number of keys can be removed to operate other interlocks. Only when all keys have been returned does this unit allow removal of the initiating key. These key exchange boxes are purely mechanical, however they can be designed to house any kind of electromechanical setup including limit switch or linear solenoid magnets.
