Assembly

Trim the leads of the 95SQ015 diode (D1) to exactly 3/8" (9.5 mm) as shown in Figure 1A.

 Fold D1's leads downward at right angles, keeping them very close to the body of the diode.  Then

use needle-nose pliers to form the leads as shown in Figure 1B.

 Place D1 across the terminals of the SPST slide switch (S1) as shown in Figure 1C. Adjust the

spacing between the diode leads so that they lightly grip the two switch terminals.

 Make sure D1's cathode lead (banded end) is not touching the third switch terminal. Once the switch

and diode are positioned as shown in Figure 1C, solder the diode in place.

Figure 1

Orient the 8-cell battery holder as shown in

Figure 2. The holder's wire leads exit at the pair of
small round holes identified by the arrows.

To provide better strain relief for the leads,

route them as shown in the drawing. First, insert the
leads through the two round holes near the first pair.
Then pull the leads out through the rectangular hole.

Note:

 Your holder might have a slightly different

hole configuration than the one shown. You should
still be able to route the leads in a similar way.

Cut the battery holder leads to a length of 3"

(7.5 cm), measured from the point where they
emerge from the rectangular hole. Remove 1/4" (6
mm) of insulation from then end of each lead, then
tin the strands very lightly with solder.
