[Healeys] Throttle Switch

[Bob Spidell]

Simon,

I've had one apart--it's a set of points with a cam on the shaft to open 
and close them.  Just test for continuity in one position and lack 
thereof in the other (check resistance, too--if it's high the points are 
probably fouled).  You can open them up--gently--and clean the points if 
you're careful not to break the tabs (I'm one for one).
