Frequently Asked Questions
Q: What does "momentary self-reset" mean for this push button switch?
A: A momentary self-reset switch means that the circuit is only activated while the button is physically pressed. The moment you release your finger, the internal spring mechanism automatically returns the button to its original position, opening the circuit again. This makes it ideal for applications like engine start buttons, doorbells, and short-trigger electronic controls.
Q: Is this 8mm push button switch waterproof, and can it be used outdoors or on motorcycles?
A: Yes — this metal push button switch features a brass nickel-plated housing that is resistant to corrosion and moisture, making it well-suited for outdoor use and automotive/motorcycle applications. The robust alloy construction ensures reliable performance even in environments exposed to the elements.
Q: What panel thickness or mounting setup does this switch require?
A: The switch requires a standard 8mm (0.31 in) mounting hole. It comes with a matching locking nut to secure it firmly to your panel or enclosure. The thread length is 7mm (0.28 in), so it is compatible with most standard panel thicknesses used in DIY electronics, automotive dashboards, and enclosure builds.
