Frequently Asked Questions
Q: What does NO and NC mean on this emergency stop push button switch?
A: NO stands for "Normally Open" and NC stands for "Normally Closed." This switch features one of each contact type (DPST – Double Pole Single Throw), allowing it to simultaneously open one circuit and close another when pressed. This makes it highly versatile for safety interlocks and automation control panels.
Q: Is this emergency stop switch suitable for outdoor or wet environments?
A: Yes — this push button switch is designed with a waterproof construction, making it suitable for use in damp or outdoor industrial environments. Its aluminium alloy and robust plastic-metal body also add to its durability in demanding conditions.
Q: What wire terminals does this switch use, and how do I wire it?
A: The switch features 4 screw terminals — two for the NO contacts and two for the NC contacts. Simply loosen the terminal screws, insert the appropriate gauge wire for a 240V / 5A circuit, and tighten securely. Always de-energise the circuit before wiring and follow your local electrical codes.
Q: Can I use this switch to control a contactor or relay in an automated system?
A: Absolutely. This emergency stop push button is specifically designed for use with electromagnetic starters, contactors, relays, and a wide range of automatic control electric circuits — making it an ideal safety component for industrial and DIY automation projects.
