Battery Switch FAQs
What’s the difference between the red and yellow knob versions?
The red knob is typically used for main battery isolation, such as disconnecting the starter battery. The yellow knob is often used for auxiliary or secondary battery systems, like house batteries or accessory circuits. This colour coding helps users quickly identify and manage different battery banks.
Can I use the yellow knob switch for my starter battery?
Yes, technically both switches function the same. However, using the red knob for starter batteries and yellow for auxiliary systems helps maintain a clear and safe wiring setup, especially in multi-battery installations.
Is the yellow knob version suitable for marine use?
Absolutely. Both versions are ignition protected and weather resistant, making them ideal for marine environments. The yellow knob is especially useful for isolating house batteries used for lighting, navigation, or refrigeration.
Can I mix red and yellow knob switches in a cluster?
Yes. These switches are designed to be clustered together, and using different coloured knobs can help visually distinguish between battery circuits—reducing the chance of accidental disconnection.
Does the knob colour affect the switch’s performance?
No. The knob colour is purely for identification and safety purposes. Internally, both switches use the same high-quality components and offer identical performance.
Can I replace the knob if it gets damaged or lost?
Yes. The knob is removable, and replacement knobs (red or yellow) are available separately if needed.
