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
