Model PC — Pull Cord Control


The Model PC is a rugged safety switch that provides a quick positive shutoff of dangerous equipment in emergencies or normal operation. It is actuated by a cable pulled by endangered personnel. The output contacts of the Model PC can control up to two separate circuits – one for machinery shutdown and one for alarm.


Safety-minded operators of conveyors, production lines, elevator equipment, assembly lines, material handling systems, cranes, and more consider it a must for employee protection. Most states have safety statutes that require these switches on conveyors and related equipment. American National Standard Institute recommends their use in ANSI standard No. ASME B20.1 - 2012-5.11. This ANSI standard will likely soon become part of the William-Steiger Act of 1970- the OSHA act.

Technical Specifications

  • The housing is cast aluminum, with optional epoxy or polyester powder coating available (for additional corrosion resistance).
  • Single-ended units are actuated via a cable pull from one direction, while double-ended units can be actuated from either or both directions.
  • The model PC units come standard with a 16 lb. pull force, however units can be manufactured with a 25 lb pull force. Add "-25" to the end of the model number.
  • The unit is mounted on the conveyor by drilling (4) 13/32" diameter holes.
  • General purpose (weatherproof) units and explosion-proof units have (2) 1" NPT conduit openings.
  • The units with "S" type microswitches (SP/DT) have dry, unpowered microswitch(es) rated for 20A @ 120 VAC, 240 VAC, and 480 VAC.
  • The units with "T" type microswitches (Two-Circuit Double-Break) have dry, unpowered microswitch(es) rated for 15A @ 120 VAC, 240 VAC, 480 VAC, and 600 VAC.
  • Highly-visible red polyester powder coated flag arm for quick identification of actuation.
  • Optional red warning light available for dark or remote locations.
  • The ambient temperature range is -22ºF (-30ºC) to 104ºF (40ºC).
  • The general-purpose units are rated NEMA type 4/4X weatherproof and corrosion-resistant. Explosion-proof units are rated NEMA type 7/9 for dust ignition-proof and vapor explosion-proof. The special dual-rated "D" units meet NEMA type 4 weather-proof, NEMA type 4X corrosion resistant, and NEMA 9 type dust ignition-proof.
  • The general-purpose controls are IP65 compliant.
  • Most models are UL listed and/or CSA certified.
