A roller-operated limit switch transfers equipment motion through a roller actuator to its electrical contacts.

## What it represents

A roller-operated limit switch transfers equipment motion through a roller actuator to its electrical contacts. The schematic names the mechanism while the GA or mechanical detail determines the roller location.

## How to read it

- Check the actuation direction and travel against the mechanism detail.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

## Information to show or reference

- Identify roller position
- State contact action
- Reference travel and overtravel

## Important distinction

A roller mechanism is different from an electronic proximity sensor.
