Customer questions & answers

Question:

Is it necessary to fuse a 12 volt wire going to a toggle switch to a 30amp relay?

Answer:

Yes, you should always fuse a wire coming from the battery, regardless of where it's going.

Question:

I have an amplifier fan that draws less than 1 amp of current. Is a relay necessary or should I just hook it up to a switch? - by Luis

Answer:

I see no reason to use a relay in this case. I'd simply use a switch, as long as the switch is capable of handling 1 amp of current.

Question:

which pin would generally be common contact, open contact, and close contact - by Kory (vancouver, wa)

Answer:

Please accept my apologies, but I don't really understand the question.

A relay basically works like this:
When the coil (Pins 85 and 86) is energized, Pins 30 and 87 will be connected.
When the coil is not energized, Pins 30 and 87a will be connected.
