That is not how my 3PDT switch is soldered now... :S

This is what it looks like


... Basically wire your new 2LED ground to the ground of the old LED

Yes.. thanx.. i know how to do it now.. its pretty cool..now its works great, when pedal is off its not possible to activate the LED for the clipping switch, and when the pedal is ON the LED for the clipping comes on to.. :D

Some call me switch master ... i've learned and done enough of switches already ...

This is how it works now..

I could not get the DIY Circuit Layout program to work so i had to draw one by hand, this is pretty much what i am talking about will be a clipping footswitch with a LED indicator.

A leed needs a resistor.. how do i calculate what resistor i should have ? RIght now i use a 1k resistor and that seems to work fine with 9 volt.. some ppl say that i need a different resistor for a standard LED.. so what to do ?

Up to you man  :icon_mrgreen: 1K is fine since you aren't designing it for battery use .
If it was for battery use i would take a water clear super bright led and use a pot to see what is the sweet spot  :icon_mrgreen:

In the 3PDT test i did in the video i used 1k resistor for two LED´s... and just to test it i was using a battery and it didnt burn up the LED´s, but what if i wanna run a battery... isnt 1k a little to smal value for LED then ?  What do u use ?

Perkla

For battery use i think i would need to have like 300ohm resistor or something like that.. most online calculators tells me like 290-360 ohm or so.. :S

Perkla

So i think that a 350 Ohms resistor on the LED should be good for a pedal that is running on both 9 volt battery and 9 Volt DC...

Perkla

A 1k resistor give much less light than a 100R resistor does when its about standard LED´s, the 100 ohm resistor let more voltage pass through the LED and in that case it will dry the battery out quicker than if u are using a 1k resistor, so in my case i am pretty safe with 1k resistor for using both 9 volt battery and 9 Volt DC... i think ?

Yeah ... but i will switch to water clear LED's at any rate . They're bloody bright even at 2.2K

So a standard green or red are giving lower light at the same power as a clear one ? 2.2K is not possible with my LED´s... to dark.. 1k is almost to dark but works for me, 100R is possible.. but will drain the battery faster..

DavenPaget

Use water clear's .
Let me prove to you they are bloody bright ( this is of 2 Series LED's @ 9v , 150R )

Thats bright.. but i would like colored LED´s, Green and Red ones ...

Ok.. yes i understand what u mean now.. i know there is clear LED´s  hahaha.. u are right about that, they are brighter than the satin ones

Perkla

With a 1k resistor for my standard green LED and 9 volt battery i get 2.27 Volts and the LED´s maximum voltage is about 5 volts (even though its way to much in my opinion).

It must be possible to simulate a 3pdt switch with 3 SPDT switches and get the same function if all 3 SPDT switches are switched at the same time.. ?

You could attach a "bridge" a hard one to all 3 switches if it is a toggle .
But if it's a stomp , attach a stomp "bridge" but usually SPDT stomps are expensive . and most likely unfindable .
