THE PRODUCTS
Pull wire emergency stop switches are used
in industry to provide an emergency stopalong conveyor lines as an additional safetymeasure on conveying systems. If an emergency arises at the conveying system, it
must be possible to shut down the systemfrom anywhere along the conveyor line. The
pull wire emergency stop switch is actuatedby pulling a pull wire provided for this purpose. The pull wire emergency stop switch- pull wire "system" is designed such that awire break also results in an emergency
shutdown.

Position switches for belt misalignment areused along the edge of the belt on each side
to monitor for belt drift on belt conveyingsystems. If the conveyor belt drifts, theedge of the belt touches the roller lever on
the position switch for belt misalignment.
Depending on the deflection, a pre-warning
is signaled or a shutdown is triggered.
