Strong comparison table
📊 Pick the configuration that matches your control board inputs and site rules.
| Option | Command style | Typical terminals | Best for | Main advantage | Watch out | What to send us |
|---|---|---|---|---|---|---|
| Option A, momentary pulse | Pulse, returns after turn | COM + SBS, STEP, or START | Most shutters and gates with step-by-step input | Fast and simple for maintenance teams | Not ideal when you need separate open and close | Photo showing SBS, STEP, or START label |
| Option B, maintained 2 positions | Maintained, stays on position | COM + OPEN, or COM + CLOSE | Industrial sites with strict operation rules | Clear open-only or close-only control | Wrong choice if the board expects pulse only | Photo of OPEN or CLOSE plus COM |
| Option C, maintained 3 positions | Maintained with neutral stop | COM + OPEN + CLOSE | Sites that need separate direction control | Direct open and direct close | Needs correct board support | Photo of OPEN and CLOSE plus board model |
| Alternative, push button station | Button press | COM + START | Indoor staff-only areas with no key requirement | Lowest friction operation | No access restriction | Confirm if you need access control |
