Step 8: Install one LED indicator light
The LED mounting bezel consists of two main parts: A ring
that the LED fits into, and a plastic plug that goes over the
LED from the back side to keep it in place.
Like some of the caps and diodes, the LED is polarized and
has to be installed in a specific direction. One side of the di-
ode has a flat edge, indicating the negative lead. Another in-
dication is that the negative lead is shorter than the positive.
Install the mounting bezel through the front of the enclosure.
From the inside, slip a lock washer and nut on and tighten it
up using a
3/8" socket
. Insert the LED into the bezel so the
flat side (short lead) faces the hole for the footswitch. Feed
the leads through the plastic plug, press the plug down until
it’s tight in the bezel. The LED will be held in place when you
solder the leads to the switches and circuit board. For a more
secure mount, you can run a bead of clear silicone adhesive
around the plastic plug.
