Which Type of Limit Switch

[Clive S]

Hi Eddy. I'm confused, why do i need a separate 5 volt psu, when my BoB is already putting out 5 volt. On the board there are terminals for 5 limits but only two wire each, + & -, Am i reading it wrong or what?

I don't know your BOB but you have to power it from somewhere I and others are assuming it is powered from a 5V source if it is powered from 12V then you can use that to drive your sensors.
Can you confirm what the BOB is powered from? ..Clive
