MOLOSswitch coupling systems of MOLLET are equipped with mechanical or inductive limit switches in order to signal the coupling situation during the filling process at silos and tanks or at coupling stations. The coupling with internal thread has a built-in limit switch with metal housing. During the coupling of the counter coupling or hose coupling the limit switch will be actuated. Blank caps do not activate the limit switch.
