I want a micro switch that I will connect to a battery operated buzzer
that will sound when a door is opened. I dont understand the technical
aspects of electrics but would something like the above work ok off say
a couple of AA batteries.


Yes no problem.

I'd avoid reed switches. They're very fussy and tend to fail when used like this. Also when used as door closed detectors, gusts of wind, warping etc result in false alarms too.
