Frequently Asked Questions
Q: What does "momentary" mean for this 16mm push button switch?
A: A momentary switch is only active (ON) while the button is physically held down. As soon as you release it, the circuit returns to its default OFF state. This makes the 16mm momentary push button ideal for starter buttons, horn buttons, and trigger-style control applications where you only need a brief electrical connection.
Q: Is this LED push button switch compatible with 12V car and truck systems?
A: Yes! This switch is rated for DC 12V and DC 24V, making it fully compatible with standard automotive 12V and heavy-vehicle 24V electrical systems. Its IP55 waterproof rating also means it can be mounted in engine bays, on exterior panels, or in other environments where moisture and dust are a concern.
Q: What panel hole size is needed to install the 16mm push button switch?
A: You need a 16mm diameter hole in your panel for installation. The brass metal body threads securely into the hole with the included nut, ensuring a firm, vibration-resistant mount on dashboards, control enclosures, or custom project panels.
