What switch should I use?

[ryanman127]

I'm trying to make a DVD burner laser just for fun but can't think of switches to use.

Would these work?

I'm also wondering what battery I should use for a 24x DVD burner.

Please tell me what the switch or battery is called. (Links for the item is preferred)

You're worrying about the wrong things. What's the host? Heatsink? Driver? Got a lens?

 

[Things]

^ Yep. Switches are the least of your worries, you're going to need a driver, module, lens and a heatsink before you can even think of powering it up.

you cant switch that on and off fast enough to regulate a safe current.

You'll learn a goob bit from this thread and if laser building is something your really interested in getting into.

You still don't answer my question. I will be putting in a metal can and use modules from online and swap the diode.

No problem with the shown switches. The red laser use a few hundered mA current and that isn't enough to stress the switches.

The switches are fine. As for a power source the battery is dependant on what driver you want to use. You don't hook a laser diode directly up to a battery unless your goal is to see how quick you can blow your diode. You will have to use a driver circuit to regulate the power supply to the diode.

A good source for diode drivers is this website:
