Enabling Switches
Bulletin 440J
The new Allen-Bradley Guardmaster 440J Enabling Switch allows personnel in the dangerous area around a machine to control hazardous machine motion. This hand-held 3-position switch is ideal for use in robot cells during maintenance, troubleshooting, programming and testing. In the first and third positions the switch sends a stop signal to the machine; in the second position the switch slows the machine while initiating all other protective measures. In the event that the personnel lets go of the switch or squeezes it in a panic, the stop signal is issued, protecting the worker from harm.
