Safe signalling and monitoring
Safety rated limit switches and Safety switches for hinged guards
Position or limit switches are used with movable machine guards or detect the presence
of materials. These switches feature positive
break contacts which make them suitable for
safety applications.
Position Switches
1-112
Hinged switches are used to monitor the
position of hinged safety guards. They prevent
machine operation while the door is ajar.
