Should I use a Hall Effect Sensor?

I am trying to create a simple project that will turn on or off a 3.2v LED light (latching) by the waving of a magnet nearby.  I want to use 2 button cell batteries to power it.  Does anyone have a suggested hall effect sensor or durable latching reed switch (not glass because I need it to be fairly rugged) you would recommend?  I am not too familiar with all the electrical specs/requirements, so I don't know which one to buy!  Thanks so much to anyone for your help!
