Thread: Wiring up worklights using Disco Switches

I have a YUG000470LNF and want to use it for additional driving lights but not sure how to wire it using High Beam as a trigger.
I tried on test bench but no success.

That's a heated rear screen momentary switch which works on the earth path, to use this for driving lights you need to make the relay self maitained after you triggered it and the driving lights will turn off only when you turn the main beam off otherwise a more complex scheme is needed... so if you are pleased with this kind of function i'll tell you what to do

Thanks for the feedback.
I have two of these switches and one will use for work light and the other for driving lights. I already have YUG000540LNF in the car for the front driving lights and works fine.
The schematic for work lights shown below, works fine and triggers the relay after a bench test.
So, yes I wouldnt mind using the second for the roof rack driving lights.
I also have a hill descent switch as per drawing which could modify for driving lights.
Not sure which is best option.

Thanks for your assistance

As i can see from the scheme with the YUG000470LNF with that setup it will trigger the relay as long as the button is pushed but the relay will open when you release it being momentary switch also it's the other way around cos this switch was built as to switch the earth from pin 4 to 1 not the live so if you want it to work as it should you must connect live to pin 5, earth to pin 4 which will be switched to pin 1 and at the relay you have to bridge the output 87 which is supposed to be earth with 85 as the relay to stay on after the swwitch was released... though you can use it as in your scheme too just bridge the live output from 87 to 86... i presume that you know that the pinout is not like you draw it cos 30 - 87(contact) and 85 - 86(coil) are opposed on the relay

Sorry
I didn't mention that both switches are latching, not momentary.
Does this change the wiring method?

Sorry, i confused the HRW switch with a D2 one... for latched switch the scheme is OK

So, how do I wire the yug000470 to trigger relay via hi beam?

I'll draw you a scheme
