USEFUL INFORMATION www.krausnaimer.com USEFUL INFO 242 MAIN CATALOG The principle of a cam switch The cam switch is a hand-operated switching device, in which a rotary movement of the handle, on an axis slice with projections, is transmitted. About these projections, also called cam, the rotational movement is converted into longitudinal movements of the plunger. These, in turn, open or close double-break contacts. Most cam switches have two contacts in a switching chamber, the so-called escape. At a total switching angle from 180 °, it allows the use of a second cam plate one from each other independent actuation of the two contacts. The switching angle between the positions is specified via a star in the detent mechanism. Within this, also a stop is located that limits the total switching angle of the rotation via another cam. This structure allows a modular principle, which upgrades a few items almost up to an infinite number of custom switching programs.
