HI, I'm wiring a voltage selector to a dual transformer power supply and to be honest it's all guess-work.  Can someone please tell me the correct way to hook it up?

Here's the info:
The power transformer has dual primaries: 115V black-brown and 115V red-orange.
For 230V operation brown and red are connected together, and black + orange are connected to the mains.
For 115V operation connect black+red together, and connect brown+orange together.
Solder black+red to one tab of the mains, and brown+orange to the other.

I'm using the selector attached below.  How should the 6 wires be connected to the 4 pins on the selector?

Thanks for taking the time to help!

I am a little apprehensive about encouraging you to dive in if this isn't already obvious.

black to 1
brown to 3
red to 2
orange to 4

in 115v per switch schematic  pin 1 connects to 2 (black to red) and 3 connects to 4 (brown to orange)
in 230v pin 2 connected to 3 (red to brown).

mains connect to 1 and 4 for both voltages.

IF THIS ISN"T CLEAR AND YOU ARE UNCOMFORTABLE get some help.

I hope you have a fuse in the mains lead.

Thanks John,  that's what I did.  I just wanted to double check.

I was just unsure about connecting both the black and mains to 1 (and orange and mains to 4) because it seems like this will put the voltage straight thru the solder point and not thru the switch.

Appreciate the help!

wha.... ????

Of course the mains gets routed through fuse and on/off switch before it hits the voltage selectro switch.

Are you trying to scare me?
