Diode wiring
Which end is which?
I know one end has the white stripe, but which is it?
Thanks,

don't know how to describe it properly, but thats the end goes AWAY from your switch etc
the stripe doesn't let current through it
(I believe!!!!!)

The end with the stripe is the cathode. In terms of conventional current flow (i.e. positive to negative), current will flow from the non-striped end
to the striped end, but not the other way.
Another way to think about it is the cathode (striped end) must be at a lower voltage than the anode in order for the diode to conduct.

Assuming there are no other electronics involved in your particular application, try it both ways.One will work the other wont!
