Frequently Asked Questions
Q: What is the difference between the momentary and self-lock functions on this push button switch?
A: In momentary mode, the switch is only active while you press and hold it — releasing the button breaks the circuit. In self-lock (latching) mode, the first press turns the circuit ON and it stays ON until you press again to turn it OFF. The PBS-11B supports both modes, making it versatile for a wide range of circuit applications.
Q: What panel hole size do I need to install this 12mm push button switch?
A: You need a 12mm diameter mounting hole in your panel or enclosure. The switch threads or clips in securely from the front, and the 2-pin terminals on the back connect directly to your circuit wiring or PCB.
Q: Is this push button switch suitable for both AC and DC circuits?
A: Yes. The PBS-11B is rated at 3A and 150V, which covers many common low-voltage AC and DC applications including hobby electronics, small appliances, computer panels, and custom control boards. Always ensure your specific application's current and voltage requirements stay within the rated limits.
Q: Can I get this switch in multiple colors for a single order?
A: The switch is available in Black, Blue, Red, Green, and Yellow. Select your preferred color when adding to cart. If you need multiple colors, simply add multiple units in your desired color selections.
