relays..

Post by mat »

I'm still struggling with the boost and channel relay wiring. I have a 4PDT switch that I would like to put on th place of the Rock/Jazz switch to handle the switching between panel switches or relays.

I have been stucked on the place to figure out what wire also (despite the input to the switch/relay) the 4PDT should cut/connect. I drew a picture of my 'thinking'.

I think I should connect the matching pins on the panel switches/relays but not the wires that are disconnected with 4PDT.

btw. I'm using Normsters layout http://bad-domain/Pics/Bassman_Dclone_LayoutV3.jpg

I have read everythink conserning relays on the forum but seems not to get further on this one.

Any ideas ?

cheers,

Why switch between functions like that is the real question.

Wire the relays like the back of the panel switch. BEING MINDFULL THAT YOU ARE WIRING THEM ELECTRICALLY THE SAME NOT PHYSICALLY THE SAME. sorry for yelling like that.

Then use a single pole switch on the panel, in parallel with the foot switch to switch in HRM or PAB of whatever.

There's an old saying in control work. "Parallel your starts and series your stops". That may not mean much to you but it's what you'll be accomplishing here. You want to Parallel the two ways to energize the controling relay. The switching functions are all handeled by the relay not by the panel switch any longer. Study Bob I's layout. Though incomplete, wiring wise, he shows a spst switch on the panel and the relay on the board.

If you follow this approach, you'll place the panel switch in the off posistion and the foot switch will then work. If you place the foot switch in the off position, the panel switch will work. But you will not be able to turn off PAB with the foot switch in the energized position and vice versa. But why in the heck would you need to do that. If you unplug the footswitch, the panel switch is automatically the one with the function.

Loose that 4pole switch and return to where you were with the relay wired properly and use only one side of the panel switch to bring in the relay or not. Then wire the two wires from the contacts in the footswitch to the same spots on the back of the panel switch. They are then in parallel.

Dan, I think I got it.. finally :oops:

I wired the relay as You told. Earlier I wired them both electrically (panel and relay) the same way ?!?
I have not wired the panel switches yet, but I got the idea.

I still have the led wired wrong ( both leds doesnt light at the same time, but I think I'll manage that one by myself.

Again, BIG thanks 8) 8)
