ABSTRACT:
There is disclosed an improved actuator215, and an operating key100for use in the actuator215. Known actuators suffer from a number of problems such as limited functionality and limited radius of operation. Accordingly, the present invention provides an operating key100for use in an actuator215, the operating key100comprising a key body105and a key element110and means to adjust an angle of inclination of the key element110relative to the key body105, the adjustment means having first and second resilient biasing means115, 120. The invention further provides an operating key100comprising means to at least partially rotate at least part160of the key element110around an axis extending from the key body105. The operating key100is thus a “universal” key, which may be used in horizontal or vertical hinged doors, though is not limited to such use.
