Wiring Question

[Coonce-Ewing]

this may be a silly question, but when wiring a circuit does it matter which side of the circuit the switch is on? (positive or negative)?

I am soldering some circuits with inline switches and I wanted to make sure it wasn't an issue before I went ahead and did it.

Wiring conventions say the switch should be on the positive side of the circuit. This allows you to use a common ground plane when using the power supply for multiple circuits.
