Normally the contacts oxidize and get dirty over time if they are not 
switched frequently.  The oxidized contacts do not make a good contact 
and the other beam does not come on because of an open circuit.  Working 
the switch will usually get it to work after a while.  Once the contacts 
become corroded they can be problematic.

The switch is not likely to be your shorting out point.  Check for 
debris build up around the external foot switch connections and at the 
headlamp subharness.

The bulbs are the resistive load.  If there is an internal short that 
cuts down the filament resistance you could draw more current than you 
generator could produce.
