Hi there,

my brothers making a coded power switch for his pc, and wants to know how much voltage goes through it, my guess was 3.3v but am i right? is it the same for the leds also?

Many thanks

That was the most painful thing ive ever DMMed.

Mine IN9 reads 3.2v on the PTM swtich. Ofc its 0 when closed

He using transistor or relay to make the connection?
 
Like Ham mentioned its around 3V but only as long as you push the button, Also it dosent matter which side is + or -.
