Interlock switch

[furumoto]

Hi,
I'm an educator and a newbie to laser cutting. I recently purchased a 40w Chinese laser cutter that does not come with an interlock switch on the cover. Since I want to use it with ever curious and not always wise middle school students, I really need to install one. Does anyone have any recommendations on a good affordable switch I can purchase?

Thanks, LF
