 Posted: Thu Dec 07, 2017 5:06 pm Post subject: Clever Wiring for Lamp Dimmer |
 |
|
Folks,
I have ten backlit switches in the panel of my plane. I need to wire all of them to the same dimmer, see the diagram on page 4 of the attached AeroRockers Circuit Diagrams, specifically the red line to the PULSE-WIDTH DIMMER box. The switches have Faston tabs. Is there some clever way to wire this? Do I just build something with a Faston terminal at one end for the dimmer and then 10 wires coming out of it, all tied up into a bundle, each with another Faston terminal?

Maybe you can wire a running string of fast-ons with two wires coming out of each fast-on? It reduces reliability to wire in series like that, but switch illumination is relatively(?) non-critical..

How about using Bob's concept for power and ground buses based on a D-Sub connector, but use it to tie your switch illumination lines together? His example uses a DB-25 connector, but you could substitute a DB-15 since you need fewer pins.

Get both male and female connectors. Bridge all of the pins together on one of them, then solder your wires to the solder cups on the other one. Mate the connectors and you've got a switch illumination bus.

That would work fine, or for wiring convenience, you could do multiple joints using the same technique. Say, 3 in the 1st faston, and 3 or 4 into a butt splice on the end of each of the 1st 3.

Question from a neophyte....does the dimmer not create some kind of electrical "noise"?

Some do, most don't . . . but there is no 'general rule'
[img]cid:7.1.0.9.0.20171208131056.0580fd50(at)aeroelectric.com.0[/img]
Illumination feeders to multiple swithces
can be 'daisy cahined' with short segments
of wire crimped into the fast-ons as suggested
above.
Eric Jones offers a little dimmer assembly (noise
free) that would work nicely with this task.
