Default Need selector for 4 pin input.

Hello,

I have a pcb that has 4 pin inputs and depending on the combination that is closed it selects a setting. Can someone help me out and show me what type of switch I can use on this to easily select at least 3 options from a switch/button selector.

Thanks.

You can buy small switches which have 16 (or 10) positions and set 4 outputs according to a binary pattern. Look for hex switch or BCD switch.

No. That is just an ordinary rotary switch. Google hex switch, or whatever the Spanish is for this. (hex = hexadecimal, BCD = binary coded decimal)

Found this http://www.mouser.com/ds/2/26/PT65-372142.pdf

How would I match the pins on the selector to the ones in the pcb? Or just solder them and figure out what decimal value they stand for and that's what I choose in the selector?

I'm going to go with the normal switch because it's simpler to use. I have to use more wire but I don't have to know what decimal number to select on the coded to select an option...

Thanks for the help.
