Hi I have only been able to making this "power" distributor by using relays, but there are no reason for using relays at all, any other solution would be great! Maybe using some BJT's?
In the schematic can you see what I am trying to do:
There are 4 push buttons that lead power to a 3TSP, when that pushbutton is pressed, do the relay latches and connect the Selector power and turn a LED on.
Above the pushbutton are there some other relays to "de-latch" all the other relays.
On the first relay, by the first push button are there a capacitor, to always turn on ch 1 if the unit has been turned off.
I have made a simulation of the circuit and hope you can please tell me, how I can get rid of K1 by using something else, preferable a small THT component, like a BJT.

Relays are great for power switching but anything with push-buttons is best served by an Arduino.
Arduino (Uno or Nano), USB charger for power, push-buttons, relay board, LEDs with resistors.
A Nano is just a compact Uno.

Yes an Arduino is great for many things but everything can almost be done by these units. Just like a printer is best for painting. Just make it on the computer and lean back. I do just feel that both the Arduino and the printer takes away the hart of it all, the construction, the problem-solving and the fun in trying to make something yourselves. It's a bit like saying "look I have mowed the lawn, I pressed a button on the robot-lawnmower" 🙂
