Frequently Asked Questions
What does DPST mean in these switches?
DPST stands for Double Pole Single Throw. It means the switch disconnects both live and neutral lines simultaneously ensuring complete power cutoff for safety in high wattage applications.
Can I use a 12V switch for 120V AC?
No you must match the switch voltage rating to your circuit. Using a 12V DC switch for 120V AC can cause failure or fire. Check the product rating before installation.
Why does my LED stay on when off?
This can happen if the LED shares a terminal with the load. Look for switches with a separate negative terminal to prevent current drain and ensure LED only lights when switch is on.
How do I determine the cutout size?
Check the product specs for panel cutout dimensions. Standard sizes include 30x22mm or 12mm hole. Ensure your panel matches these measurements before purchasing.
Are these switches suitable for boats?
Yes waterproof models with IP65 ratings are ideal for marine use. Ensure the switch is rated for 12V or 24V DC and has corrosion resistant materials.
What is the benefit of a 3-pack?
A 3-pack allows you to install switches for multiple circuits. It often offers a lower unit cost than single packs making it economical for complex projects.
Do I need special tools to install?
Most snap-in models require basic tools like a drill for the cutout. Blade terminals simplify wiring so soldering is not always necessary.
How do I know the LED voltage?
Check the product listing for lamp voltage. Many 120V AC switches use lamps that work on 110V to 250V AC matching typical household voltage.
