The Black & Webster/Air-Hydraulics Protectoswitch is
an ideal way to protect your operators from pinch point accidents
while operating machines such as riveters, presses, punches, eyeletters,
stakers, and spot welders.
A simple cost-effective way to increase operator confidence and
productivity, improve safety records and reduce time lost on the
job.
When the operator closes a hand or foot switch to activate the
machine, the Protectoswitch intercepts the start signal and automatically
drops a probe around the work area. If an obstruction is sensed
the machine will not fire until the obstruction is removed. If
the work area is free of obstructions, the probe falls to its
full stroke which closes an actuating switch to fire the machine.
