Hullo, I wonder if someone could answer a question which seems simple but which I have struggled to find the answer to?
Can I use a single pole double throw switch as a digital input device to a picaxe chip without the resistors usually shown in diagrams which use a simple momentary on switch. In other words if the common part of the switch is connected to the picaxe pin and the other two are connected to the +ve and 0v rails respectively will I encounter any problems. I suspect not because unlike any open switch in which one state will be floating unless it is tied to one of the rails a spdt switch arranged like above will either be fully +ve or fully grounded. Am I being naive?
Thanks in advance
