You've seen how handy our window blind and shade systems are, now you can use the same safe, low voltage technology to open and close your windows. It is simple to adapt this unit to most types of windows and skylights because it does not need to rotate in any way like hinged units do. The flex link direct push drive has a 300mm stroke (~12"), the opening/closing max force before obstruction sensed is approximately 20 lbs (9 kg), current consumption is ~1.5 A, protection class is IP32. These units have been stress tested to over 3,000 openings.
If you are planning to use this for a skylight opener, note that you can check the force required to open the skylight by standing on a bathroom scale and pushing up on the skylight with a long broom handle or other suitable pole. If your skylight is heavier than the actuator capacity, you can offset the extra weight with gas shocks, torsion springs or external counterweights.
PLEASE NOTE: Window and skylight openers can be dangerous to children and adults as they normally have a considerable amount of force that is used to draw the window closed and provide security. There is more than enough force to crush fingers of small children and/or cause injury to adults, pets, or other animals.

The linear chain actuator pushes straight out from the fixed housing which lines up unobtrusively with your window frame, fastened in place with mounting screws. Attach the end of the chain actuator to the window with two screws, connect the wired wall switch control wires with the provided connectors, plug in the power supply and you're done!
The wired wall switch controller can operate about 5 of these simultaneously (you'll need a 12v battery or bigger power supply); it is NOT compatible with our multi-channel blind and shade remotes.
The wired wall switch can also be interfaced to a building automation system using 2 relays (up/down).
Use it to control the motion of anything you want, including windows, greenhouse vents, skylights, etc. Works great with solar and 12v battery sytems too.
The stroke is also adjustable: 4" (100mm), 8" (200mm), 10" (250mm), 12" (300mm)
This switch is not a good choice for domestic applications; please see our elegant wireless remotes as an alternative.
