Power Toggle Button w/ 4 States

I am trying to create a system with a toggle switch that cycles between 4 power states. It will be used to power three 12V LED light strips. Here are the 4 power states that I want to toggle between:

  1. LED Strip 1 ON

  2. LED Strips 1 & 2 ON

  3. LED Strips 1, 2 & 3 ON

  4. All LED Strips OFF

I would ideally like to have all of this connected to a rechargeable battery pack. This will need to be mass produced (about 2000 units), so I am trying to keep the cost as low as possible. Any help would be appreciated.

Hi,

You can use atTiny85 board with minimum number of pins and write simple code for getting your required output. If you want to mass produce the product then attiny sounds quite cheap.

I hope it will help you.

Thank you so much.
