Default Installing a SPDT switch

Hey guys, I hate to ask such a simple question, but I couldn't find an answer or similar thread using the search feature.

I'm using a computer PSU hooked up to an LM317 driver, which is then wired up to a 650 nm 250-300 mW open can diode.

So, my question is, can I hook up an old SPDT slide-switch I have lying around?

More to the point, I know I CAN do it (had it all working last night), but my question is if I were to turn the switch off, and then back on, would it hurt the diode at all?

I had the switch in line with the negative wires and I just left it in the "ON" position, so when I plugged the PSU in it acted just as it would if the switch wasn't even there.

So, any downsides at all to hooking it up this way?

Thanks in advance guys, and I'm sorry if this had already been asked/answered in the past.
