Car 3 position Toggle Switch

Hi.

I am planning to replace 2 toggle switches which are 3 position toggle switches with arduino and bluetooth module. These are suspension switches, where each of the toggle switches are for front and back. Each toggle switch has 3 positions, High Normal Low.
Circuit is open when it is in Normal.

How can i replace these toggle switches with arduino. I am aware of the method using a relay. But as the module will be inside the car, i don't want the clicking noise of the mechanical relay.

Can we program the arduino to be a switch where a code can engage High or disengage. The arduino is powered separately.

I'd like help to go on with this experiment.

Thank you

You can use Power Mosfets or Transistors instead of relays but what are you using as inputs ? The arduino still needs an input to switch outputs. You could use simple push button and a series of presses. 1 normal 2 front high back normal 3 front high back high 4 back high front low ..etc. the point is you still need some input otherwise you still have the 2 switches so why is arduino needed.?

Please post circuit of what you're trying to replace. I can't really imagine what you want to do. It sounds like it can be done with two MOSFETs or transistors and two output pins, but not all too sure.

I'm planning to use bluetooth module as input. So i can control it from my phone.

MOSFET or transistors, I'll be going with it.

Thanks a lot.

Hello everyone.

I finished the project using 4 relays, Nano and HC-05. It works just like how I wanted to. Made an Android app for the Suspension.
Posting pictures below.

Thanks everyone for the help.
