These rope operated safety switches are installed on machines or conveyor belts to activate the emergency stop of the machine on every hand intervention over the rope. They allow cost saving on medium and small machines, where otherwise many ermergency stop buttons have to be installed.
Provided with self-control function, they check constantly their correct working operation, signalling by opening the contacts an eventual loosening or break-out of the rope.
These safety switches keep the contacts open after their activation till the reset push button is manually pulled.
