Enabling Switch Features
Compliant with international standards 3-position enabling switches
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 situations.
In IDEC’s enabling switches, both actuators and contacts are duplicated. When a hazard must be
stopped at high safety level, disparity of two contacts must be detected using safety relay module so
that failures such as damage or welding of contacts and actuators can be detected.
As for usability, the operating force required to shift the switch from position 2 to 3 is the same when the
button is pressed on the center or off-center. Operating force does not increase even when pressed off-
center by one finger. High durability is also provided; operating force hardly changes after 10000
operations.
