FAQs About Narva Rocker Switches
- Q: What does SPDT mean?
- A: SPDT stands for Single Pole Double Throw, meaning the switch has one input and can connect to either of two outputs.
- Q: How do I know the current rating of my Narva rocker switch?
- A: The current rating is typically printed on the switch body or specified in the product datasheet.
- Q: Can I use a Narva rocker switch for a 24V system?
- A: Yes, provided the switch is rated for 24V. Always check the voltage rating before use.
- Q: Where can I find a Narva Rocker Switch Diagram?
- A: The diagram is usually printed on the switch itself, included in the packaging or available from the Narva website.
- Q: What type of wire should I use with a Narva Rocker Switch?
- A: The correct gauge wire depends on the current the switch is handling. Consult a wire sizing chart to determine the appropriate gauge to safely handle the current load. Always use automotive grade wire for vehicle applications.
