Frequently Asked Questions
Q: What is the difference between the instant (momentary) and self-locking versions of this 16mm push-button switch?
A: The instant (momentary) version completes the circuit only while the button is physically pressed, then returns to its open state when released — ideal for doorbells, triggers, and reset buttons. The self-locking version stays in the activated (closed) position after being pressed and must be pressed again to disengage — great for on/off power controls and toggle applications.
Q: Is this 16mm push-button switch suitable for outdoor or automotive use?
A: Yes. The waterproof metal housing is designed to withstand exposure to moisture and dust, making it well-suited for outdoor panels, automotive dashboards, motorcycles, marine equipment, and other environments where a standard switch might fail.
Q: What panel cut-out size do I need to install this push-button switch?
A: You need a 16mm diameter hole in your panel or enclosure. The switch threads through the hole and is secured with the included mounting nut, making installation quick and straightforward with basic hand tools.
