Hi. I am doing a neon install inside my car . I am hoping to connect up to 10 different types of neon and led based products inside my car. I was hoping to use a momentary switch ( like a demister switch ) as I have a spare switch on my dashboard.

What relay would i need to use and how would i connect the switch to the relay as the switch is normally open. Also would 1 relay be sufficient to to power as many as 10 items.

Many thanks in advance.

Using the diagram below you can use a momentary switch to turn on and off anything hooked to the relays.

If you need more then thirty amps then just wire additional relays off of the +output of the relay on the right.
