Key switches are a popular method of opening garage doors automatically and at the same time with a tried and tested key: As soon as you turn the key, the button is activated, which you only have to press to open or close the door. Now it is no longer necessary to get out of the car and open the door manually. This key switch column makes installing the new system extremely easy, because the contact to the cylinder is already inside the aluminum column. Three keys are also included. You just have to set up the column and connect it and the key switch will work.
