Teach Pendant Enable Switch
Requires an operator to hold a middle position to permit manual robot motion, acting as a hold-to-run safety control.
The enable switch, mounted on the back of the pendant, is a three-position device that must be held in its middle position to permit manual motion. Releasing it fully or squeezing it too hard into the third position both stop the robot, a design meant to prevent motion from either letting go in a panic or gripping too hard under stress.
This switch is used constantly during manual operation and programming, making it one of the most cycle-worn safety components on the pendant.
A worn enable switch that fails to register its center position reliably prevents an operator from jogging the robot at all, which is a common service call traced to this single component.
