Wiring help needed...
« on: February 07, 2014, 08:51:57 am »

Morning chaps,


I need to wire the following:

One red/one blue flashing HiViz 5mm LED's, and one white HiViz 5mm LED (non flashing) via a servo operated microswitch...hit it once for 'on', hit it once for 'off'.


One red/one green 5mm HiViz LED's, via an on/off slide switch. (port/starboard nav lights)


All lights will be run from a separate 4 cell 4.8v rx type battery pack.


I'm told I need to add resistors in line somewhere?


Could one of you kind gentlemen draw me a wiring diagram of what goes where, please? No technical terms, I won't have a clue what you're about, just done in common or garden sweeper drivers language.


Thanks chaps,




Rich

If I am wrong I am sure somebody will correct me. But here's how I would do it.
You need a resistor for each LED 220 Ohms for your Red LEDs and 150 Ohms for Greeen Blue and White. I do not think you will get a micro switch that locks. I use a light presure on/off switch.
If you have a Maplins or electronic shop near you I am sure they will be glad to help I just write a list and give it to the assistant in my local shop. Componant shop is a good online store to get bits from and usually quite qiuck.
now wiring put the resistor on the positive side of your LED that will be the slightly longer leg
Not very good wiring diagram but may help.

Flashing LEDs normally have a built in resistor
and can be connected directly to the supply.

Yes, self flashing LEDs have a bit of extra circuit built in to do the flashing and you get them rated to run off a specific range of voltages.  Normal LEDs need help in the form of resistors to stop them taking too much current, which kills them.  They do shine very brightly before they vanish, though.
Micro switches are just a box with a set of contacts inside, press for one way, release for the other.  When they are mounted to be operated manually on a panel, you need to fit a mounting adaptor, and this is where they can be made latching.  Its the adaptor, not the switch that does that trick.
You could look here - http://www.maplin.co.uk/p/two-pole-push-button-switch-fh67x - but I suspect that there was a mistake on the price.
