Section 4: Installation of Latch Check
Switch in Spring Release
Proceed with the following five steps:
Step 1:
Remove the spring release from the breaker prior to installing
a latch check switch by performing Steps 1 through 3 of Section 3.
Step 2:
Position the spring release as shown. Tilt the latch check
switch back to properly position it for final installation. The LCS is
shown without leads soldered to appropriate terminals for clarity
purposes (Figure 9).
Figure 9. Step 2.
Step 3:
Carefully press the latch check switch down as shown until a
snapping sound is heard. This sound indicates the switch is properly
seated (Figure 10).
Figure 10. Step 3.
Step 4:
If the latch check switch being installed is for use
internally
in conjunction with the spring release, plug the small 2-pin connector
of the latch check switch into the 2-pin plug in the spring release. The
2-pin connector only fits one way and will latch into place. If the latch
check switch being installed is for use
externally
, skip this step and
proceed to Step 5. Keep in mind that separate secondary connections
with an
externally mounted
LCS will have to be made as part of
Step 5.

repeat Steps 3 through 8 of Section 2.
