Abstract
In an electromotive control device having an end disconnect switch, two circular conductive paths are arranged on an insulating support, at least one of said paths being less than an entire circle. Wiper contacts which connect the conductive paths are electrically connected to each other and are connected to a wheel which is driven by a motor, the wheel being mounted coaxially to the conductive paths. The limit disconnect switch and thus a setting element can be manufactured at low cost by the invention.
Claims9
An electromotive setting device having a limit switch, the device comprising
- an insulating support and a wheel;
- two circular conductive paths arranged on said insulating support coaxially about an axis of said wheel, at least one of said paths extending less than a full circle;
- wiper contacts connecting with said conductive paths and being electrically connected to each other to form said limit switch;
- and
- a motor, said wheel being connected to said wiper contacts and being driven by said motor;
- and wherein
- a first path of said conductive paths has a longer portion and a shorter portion which are electrically separated from each other.
