5 SeriesAn enabling switch is a 3-position (OFF-ON-OFF) switch to allow a machine operation only when the switch is lightly pressed and held in the middle position (position 2). Because it disables machine operation when released (position 1) or further depressed (position 3) by a panicked operator, the safety of operators is ensured. Because operators use pendants in hazardous environments performing teaching, system changeover, and maintenance of robots, they must have protection against unpredictable motion of robots, and therefore teaching pendants are equipped with 3-position enabling switches.
3 –Position Operation, how it works: By holding an enabling switch, an operator can avert danger when a machine operates unexpectedly. When the panicked operator either releases or grasps tightly the enabling switch, the switch disables the machine operation in either situation. CATALOG
