Features and Applications

This slack cable style switch is equipped with a positive safety lock.  Once actuated, it cannot be accidentally reset causing dangerous equipment to restart. 

 

The cable may be extended in either or both directions with no changes required in the internal mechanism.  There is one electrical connection inside eliminating the double electrical connections typically required in two ended units employing a separate micro switch for cable in each direction. 

 

The actuation force required is simply adjusted in the field by attaching the cable to any one of the three holes provided on the switch actuating arm.

 

The standard construction of this switch consists of the corrosion resistant aluminum housing complete with stainless steel hardware, red powder coated actuation handle and stainless steel actuation shaft. 

 

These switches are usually installed with cable running in both directions from the crank type actuating arm. The cable should be supported by eyebolts every 10 feet to ensure that the weight of the cable alone will not actuate the switch. 

 

  • Recommended cable length is 100 feet maximum on each end.
  • Can be mounted in any position

A pull on the cable at any point will rotate the red actuation arm 60 degrees. The actuation arm will end in a position that is easily seen from a distance, thus identifying the actuated unit. Two spring loaded detents riding on a hardened steel cam provide resistance to arm rotation.  When the actuation force overcomes this resistance the assembly rotates 60 degrees and is locked in place by the detents. Affixed to the rotating shaft is a cam mechanism which actuates up to two micro switches during rotation.  The micro switches are held in the actuated position by the detents. 

 

To reset the switch and deactivate the micro switches, the actuation arm must be pushed in and rotated backwards.

FT is the value of force, along the cable, which trips the switch.

FO is the value of force, applied by the operator perpendicular to the cable, which trips the switch.

SD is the distance between the cable supports.

ST is the distance the cable is deflected at the time of tripping.

ST** is in addition to any slack “droop” required for set-up.

WARNING - DANGER

These products should only be used where point-of-operation guarding devices have been properly installed & maintained so that appropriate OSHA and ANSI B11.1 regulations & standards are met.  Misapplication of the products on machinery lacking effective point-of operation safeguards can cause serious injury to the operator of that machinery.
