Abstract:
A safety circuit for an elevator system includes a first circuit having a plurality of switching contacts and a second circuit having a plurality of switching contacts. The switching contacts of the first circuit are connected in series, and the switching contacts of the second circuit are connected in parallel. Each switching contact of the first circuit is associated with a different switching contact of the second circuit. The switching contacts that are associated with each other are in opposite switching states.
