Startup current is really what you'd be worried about.... those tube heaters would draw quite a hefty current until they warm up, and that can be many times more than operating current... So you'd need a switch that's many times the current rating of the set when running.

Since you're dealing with quite a bit of current, you'd want something more solid like a throw switch, especially since micro-switches are more susceptible to contact "bounce". To solve that you'd need a low voltage supply to the switch and a relay of some sort to do the actual switch-on... more parts, more cost etc.

I'd also wonder about the safety of a straight up mains switch like this... a tech servicing the cabinet, forgot to unplug it, but it's off, tilts the cabinet a bit, door falls open and *ZAP*.
Or, as in above, you're running 120V through a commonly-accessed area, more potential for the customer to get zapped if wire frays or becomes exposed etc.
