Why Choose ARMASPEC ST45?

When safety and reliability are non‑negotiable, the ARMASPEC ST45 stands out as the industry’s trusted solution. Its short‑throw design minimizes the distance your hand must travel, reducing the chance of accidental activation. The ambi‑safety interlock provides an extra layer of protection, ensuring that machinery cannot be started unless the selector is deliberately set to the “ON” position.

Manufacturers and system integrators choose the ST45 for its:

• Consistent performance under heavy load cycles.
• Seamless integration with existing control panels.
• Compliance with global safety standards.
• Cost‑effective lifecycle thanks to its robust design.

Installation & Wiring Guide

1. Turn off power to the control panel and verify de‑energized status.
2. Drill a 1‑inch (25 mm) mounting hole if not pre‑existing.
3. Secure the selector using the supplied mounting screws (M4 x 12 mm).
4. Connect the line (L) and load (N) terminals according to the wiring diagram printed on the switch housing.
5. Use a torque wrench to tighten connections to 3 Nm to ensure optimal contact pressure.
6. Label the selector position (e.g., “RUN / STOP”) using the embossed label area.
7. Restore power and test the operation—verify that the selector snaps firmly into both positions and that the safety interlock functions correctly.
