Selection Questions
How do I select the correct mounting size?
Use the panel-hole and body dimensions for the selected model, then compare them with the existing panel. Different models are not mechanically interchangeable.
Does a matching face shape confirm electrical compatibility?
No. Confirm the contact arrangement and electrical rating of the selected switch before connecting it to the control circuit.
Are matching keys or lock codes guaranteed across models?
No. Specify the required key and lock code when ordering; a similar key appearance does not establish interchangeability.
What is the difference between SH-KS-3 and SH-KS-4?
SH-KS-3 has a 36 × 36 mm square face and a 33 × 33 mm panel cutout with R5 corners. SH-KS-4 has a 42 mm round face and a 37 mm panel-hole diameter.
