Is it possible to use 2 pin push buttons instead of 4 pin push buttons ? I want to have some buttons on the project box going through resistor network to the analog pin
Don't understand, please describe what you want again.
Yes. Most tact buttons have four pins for stability and ease of circuit board design. With four pins, you have inbuild links to skip over circuit board tracks. A 4-pin tact switch is electrically the same as a 2-pin one. Leo..
I don't think ease of circuit board design has much to do with it.
Thats perfect cheers guys just wasnt to sure :)
CrossRoads: I don't think ease of circuit board design has much to do with it.
Oh yes it does!
It allows them to be laid out in a matrix on a single-sided circuit board where the two common pins provide a link under which the transverse common can pass. This is even quite useful if they are not in a matrix array as one side is generally a reticulated power bus.
If you were to observe that mechanical stability might be a more important reason, well that could be a point. :grinning:
