Quick answer: No. The approved winding range and load direction must explicitly include the intended bidirectional motion.
Can a return spring be assumed suitable for rotation on both sides of its setup position?
A return mechanism and a centered rotary mechanism impose different operating conditions. Passing through the free or reference state can change retention and curvature. Present the complete angle sequence to the designer and avoid describing travel only by its total span.
A practical verification method
Check both directional limits and the transition across the setup point using approved prototype procedures.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Check both directional limits and the transition across the setup point using approved prototype procedures. | Resolve the specific question before approval |
Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
