I'm in the process of adding a under dash A/C unit into my car and I want to change the fan speed selector switch that came with the unit to a push button type switch unit by using these momentary push buttons and some relays. I want the push button switch that I'm trying to make to have 4 buttons total. 1 button for "off" and 3 other buttons for the "low, med & high" fan speeds & I would also like for each button to cancel the other one out when another one is pressed kind of like one of the A/V selector switches. I don't like the look of the switch that came with the unit & was thinking about mounting it inside the glove box out of sight but If you guys can help me out with something to use these buttons I am going to flush mount them somewhere on the dash where they are easily accessible. Thanks in advance!
