Product Overview
Five reviewed photographs show the same red-housing structure from independent angles: complete side profile, rating-label side, upper actuator assembly, opposite housing side and transparent terminal-cover view. Some photographs are marked QM-S3-1370 while the backend record uses SH-S3-1370; confirm the supplied revision before ordering.

Buyer Confirmation Checklist
Model identity
Resolve the SH-S3-1370 versus QM-S3-1370 marking and confirm the full revision or part reference.
Electrical function
Confirm 1NC contact behavior, AC or DC duty, voltage, current, terminal assignment and controller requirements.
Mechanical installation
Check roller diameter, 5 ± 1 mm movement, operating direction, automatic return, body size and mounting clearances.
Frequently Asked Questions
Are SH-S3-1370 and QM-S3-1370 confirmed as identical?
No. The backend and physical photograph use different prefixes. Confirm the supplier's revision mapping before final selection.
Is the switch automatically resetting?
The reviewed S3-1370 (1NC) source table states automatic reset, but the supplied physical unit should still be checked.
What should be checked for replacement?
Compare the complete label, contact state, voltage and load, roller movement, operating force, housing dimensions, mounting and terminal access.
Selection note: Do not finalize compatibility from the shared S3-1370 number alone. Confirm the model prefix, contact operation and mechanical installation.
