So, basically i have 4 wires with different input/output signals working on 1.6V.
Now i need to add master switch that can disable all 4 wires, so when switch is OFF the signals will not be passed thru the wires
I draw something, hopefully u understand my idea
**broken link removed**
What is the easiest way to do that? As a newbie in electrionis i was thinking adding 4 seperate relays to do this
Another way to do it would be to use a 4pst relay, the above is a better idea, however if you want to use an allready existing switch that doesnt have 4 poles then the relay is another option.
You can use an industrial control panel switch. You can put as many switches as you like on the on/off operator. I saw one once with 11 switches on it. You can use any combination of NO and NC contacts as you need.
