Zone limit switch with three stay-put positions
The zone limit switch UGS has the features of a safety switch with forced actuation. It has three switching positions with stay-put feature and therefore retains in the last position. The zone limit switch is used to bridge the switch for locking mechanism if a door interlock is operated by stationary cams, so that the lift can move a short distance with unlocked doors. The limit switch is actuated at the roller lever by change-over cams.
