Frequently Asked Questions
Q: What does "momentary" mean for this 16mm push button switch?
A: A momentary push button switch only completes the circuit while the button is physically held down. The moment you release it, it automatically springs back (resets) to its original open position. This makes it perfect for applications where you need a brief pulse signal — such as triggering a relay, resetting a counter, or activating a contactor momentarily.
Q: Is this push button switch suitable for outdoor or wet environments?
A: Yes. This switch carries an IP65 protection rating, meaning it is fully protected against dust ingress and resistant to water jets from any direction. The IK08 rating also confirms solid resistance to mechanical impacts. It is well suited for outdoor control panels, automotive applications, and any environment where moisture or dust is a concern.
Q: What panel cut-out size do I need to install this switch?
A: You will need a panel cut-out (hole) of approximately 16 mm (0.63 inches) in diameter. The switch uses a standard bushing-mount installation with a screw terminal connection, making it straightforward to fit into most enclosures, control panels, or DIY project boxes.
