Specifications - Installation and Operating Instructions
Series CPS Cable Pull Switch
The Series CPS Cable Pull Switch is designed to provide a
switching system to isolate the power to the conveyor system or
other similar process equipment in event of a shut-down condi-
tion. A steel wire is placed along the side of the conveyor and at-
tached to the cable pull switch. When the cable is pulled at any
point along the conveyor it will trip the cable pull switch causing
the conveyor to shut down. To restart the conveyor the CPS
must be manually reset. The series CPS has a universal design
for bi-directional activation and utilizes a highly visible red flag to
indicate the switch status. The compact design makes it ideal for
easy installation.
