Frequently Asked Questions

Q: What does "momentary" mean for this push button switch?

A: A momentary switch is only active while being pressed. The circuit closes when you push the button (on) and opens again as soon as you release it (off). This makes it perfect for car horn switches, alarm triggers, and other short-duration 12V electrical applications.

Q: Is this push button switch truly waterproof for outdoor and automotive use?

A: Yes. This switch carries an IP65 rating, meaning it is protected against dust ingress and low-pressure water jets, making it well-suited for automotive dashboards, engine bays, motorcycles, boats, and outdoor panels.

Q: What panel hole size is required to install this 19mm switch?

A: The switch requires a 19mm (approximately ¾ inch) panel cutout. It mounts using the included hexagonal nut and rubber ring, which secures the switch firmly and maintains the waterproof seal.

Q: What is the maximum electrical rating for this switch?

A: This push button switch is rated for 3A at 12V DC, making it suitable for car horns, warning lights, and similar low-current 12V automotive and electrical circuits.
