MIL-C-21679(NOrd)

4.6.1 Visual inspection. - The mechanism and its com-

ponent parts shall be inspected to verify that the materials,

design, construction, physical dimensions, soldering, and

workmanship are in accordance with this document and the

drawings.

4.6.1.1 Lubrication. - The mechanism shall be inspected

to verify that it has been lubricated as specified in 3.2.2.

4.6.1.2 Assembly nuts. - Assembly nut torque require-

ments specified in 3.2.3 shall be verified by the proper

calibration setting, and use of torque wrenches. Inspection

shall be accomplished during the assembly process-

4.6.2

Components tests.

4.6.2.1

Switches.

NOTE: The contact arms of the two switches

may be adjusted after final assembly of the mechanism, if

necessary, to meet the requirements of 3.2.4.1.

4.6.2.1.1 Contact clearance. - The contact clearance of

the two switches shall be checked to determine compliance

with 3.2.4.l.l.

4.6.2.1.2 Contact force. - Contacts shall be checked as

follows to determine compliance with 3.2.4.1.2.

(a) Open pos ition. - The force of the inner contact arm

assembly against the cam shall be measured from the end of

the inner contact arm assembly. The force of the outer con-

tact arm assembly against the reinforcing angle shall be

measured from the end of the outer contact arm assembly.

(b) Closed position. - The contact force shall be

measured at the outer end of the contact arm.

4.6.2.1.3 Contact resistance. - The resistance.of each

switch at the contacts and at the terminal lugs shall be

checked with test item 4.4.1.1(c) to determine compliance

with 3.2.4.1.3.

4.6.2.2 Bottom plate assembly. - After assembly of the

mechanism, but before securing the case, the gap between

each of the pillars and the inside face of the bottom plate

shall be checked to determine compliance with 3.2.4.2.
