IMPROVEMENTS RELATING TO TRAPPED KEY INTERLOCK SYSTEMS
A key module (4) for a trapped key interlock panel (3), comprising:a) a module housing (10) mountable in the trapped key interlock panel;b) a cylinder (15) comprising a key slot (16) for receiving a key (5), the key slot extending from a front face (17) of the cylinder rearwardly along a longitudinal axis of the cylinder,the cylinder being rotatably-mounted in the module housing to permit rotation of the cylinder relative to the module housing about the longitudinal axis between a key insertion position, in which a key is free to be inserted into or removed from the key slot, and a trapped key position, in which a key is retained in the key slot,the cylinder also being reciprocally-mounted in the module housing to permit reciprocating axial movement of the cylinder relative to the module housing along the longitudinal axis, andthe cylinder being biased forwardly within the module housing;c) a cylinder retaining element (39) for retaining the cylinder in the module housing;d) a lock (25) for selectively preventing rotation of the cylinder about its longitudinal axis;e) a switch (30) for generating a signal when the cylinder is displaced rearwardly within the module housing against the bias of the cylinder by engagement of a key in the key slot; andf) an antenna (50) for receiving wireless signals from a wireless tag (6) of a key.
