3. Buzzer Switch Check
-
Remove the buzzer switch
and visually inspect it for physical damage. Should
the switch be damaged, replace it. If it appears satis-
factory, fasten the alligator clips from the continuity
meter to the buzzer switch leads (one clip per one
lead). Be careful not to bend the leads. Depress the
actuator pad until the interior points contact (Fig.
12-5).
The continuity check should light when the points
close. If it does not, replace the buzzer switch.

4. Setting the Contact Gap
-
To set the switch to the low
contact limit, insert a typical feeler gauge firmly onto
the actuator pads.
If contact is not made, adjust the switch by bending
the moveable internal member with a small screw-
driver. Adjust as shown in Fig. 12-6 to .O3 1
".
Then check the switch with a feeler gage for the "no
light" condition. If contact occurs here, bend blade as
shown in Fig. 12-7 to .024".
When the switch will make contact on the "light"
and not on the "no light", the contact gap is set on
the low limit.
CAUTION: Should the switch be used with the
contact
occurring
in the 'ho light" step, the
buzzer could then operate with or without the
key in the lock cylinder.
5. Recheck
-
With the switch properly adjusted, assem-
ble it and the lock cylinder back into the column.
Recheck continuity with the key in and out as before.
