<p>A method and apparatus for control of closures such as windows and doors. The control is achieved using a fluidic medium. The control mechanism (20) is concealed in a frame (F) with which the closure (S) is mounted. The control mechanism can be a linear actuator (20) coupled by an arm (39) to an arm (13a) of a window stay (10). Remotely controlled solenoid valves (V) within the frame (F) operate the linear actuator (20). A port (32) of the frame (F) is removable to permit access to the linear actuator (20) which is housed in a housing (33) formed as part of frame (F).</p> |
