What it represents
A cam-operated limit switch changes its electrical contact state when a defined cam profile reaches the actuator. Its position function depends on the documented cam and mechanism relationship.
How to read it
- Link the cam position to the electrical contact schedule.
- 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
- Reference cam detail
- Identify operated contact
- State normal mechanism position
A distinction that matters
Cam actuation is a mechanical input, not an electrically programmed timer.
