Safety Switches
This category covers Allen-Bradley Bulletin 440E and Bulletin 440T safety switch products used in machine guarding and perimeter safety applications. The 440E line includes UV-resistant polypropylene-covered rope cable, stainless steel turnbuckle kits, and eye bolt hardware in a range of lengths — from 5-meter configurations up to 300-meter runs — supporting cable pull safety switch installations. The 440T trapped key interlock series includes triple solenoid release units with multiple N.O. contact configurations, designed for access control sequences where physical key exchange enforces a safe order of operations. Controls engineers and machine safety designers specifying rope pull switches, cable safety systems, or trapped key interlock devices will find accessory kits and fully assembled interlock units across this inventory of nearly 2,000 SKUs.
