ABSTRACT:
The metal surfaces of a lock mechanism are covered with a shield of a relatively low thermal conductivity material to insulate the fingers of the user from direct contact with metal to prevent possible burning or discomfort while operating the lock mechanism. In a preferred embodiment for use with automotive ignition switches of the type having raised metal wings for rotating a lock cylinder, the thermal shield comprises rubber or plastic pockets or caps which are secured in place over the metal wings to enable rotation of the lock cylinder with the fingers contacting only the surfaces of the pockets or caps.
