LOCK ACTUATOR
A cylinder lock actuator 1 comprising a first and second lock cylinder and a clutch mechanism (13 Fig 2), the clutch mechanism to selectively engage either lock cylinder with a cam (10 Fig 2) held rotatably in the cylinder lock actuator, wherein the cam is held in an axially moveable manner within the cylinder lock actuator, the cam being normally in a first axial position within the cylinder lock actuator such that the clutch mechanism can engage either of the first or second lock cylinders, and there being biasing means 35, e.g. a spring, which is adapted to axially move the cam into a second position upon attack and removal of the second lock cylinder, and locking means, preferably a pin and aperture 30, 31 which is adapted to constrain the cam with respect to the first lock cylinder when the cam is in the second position, and the biasing means and locking means operate independently of the state of the clutch mechanism. The axial movement of the cam relative to the housing prevents it from actuating the lock in the second position. A torsion ring may be provided to link the clutch mechanism to the cam.
