Frequently Asked Questions
Q: What does "self-locking" mean on the KAN-28 push button switch?
A: A self-locking (also called latching) push button switch stays in its current position — either ON or OFF — after being pressed. Unlike a momentary switch that reverts when released, the KAN-28 locks in place until you press it again. This makes it ideal for applications like flashlight power controls where you want the state to hold without continuous pressure.
Q: Is the KAN-28 SMD switch compatible with 18mm and 28A flashlight bodies?
A: Yes. The KAN-28 is specifically designed for the 1812/28A form factor and fits standard 12mm panel cutouts commonly found in flashlight bodies and compact enclosures. Always verify your device's cutout diameter and switch footprint before installation.
Q: What is the maximum electrical rating for the KAN-28 push button switch?
A: The KAN-28 is rated at 5A and 250V AC, making it suitable for a broad range of low-to-medium power electronics applications, including DIY circuits, control panels, and flashlight modifications.
Q: How many switches come in one order?
A: Each order includes a convenient 5-pack of KAN-28 SMD self-locking push button switches, so you'll have extras on hand for multiple projects or future repairs.
