Safety Switches

This category covers Allen-Bradley Bulletin 440E and Bulletin 440T safety switch products used in machine guarding and perimeter safety applications.

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.
