(d) The drawings shall include in chart form the weight of a switch, the weight of a set of repair parts, and torque,
as well as length dimensions, for switching having different numbers of switching decks. The drawings shall
also show the maximum number of switching decks that can be used and still meet the high impact shock and
vibration requirements with and without rear support.
(e) A list of repair parts and special tools with piece number for each item, the name of each item, the quantity of
each item recommended for a set of repair parts (on a per switch basis), the manufacturer's ordering
identification for the item.
(f) Switch rating.
(g) List of exceptions to this specification.
4. VERIFICATION
4.1 Classification of inspections. The inspections specified herein are classified as follows:
(a) First article inspection (see 4.3).
(b) Conformance inspection (see 4.4).
(c) Comparison inspection (see 4.5).
4.3 First article inspection. First article inspection shall consist of the tests specified in table I.
4.3.1 First article samples. Switches submitted for first article shall be representative of the manufacturer's normal
production standards and methods, and shall be in accordance with the drawings (see 3.10). The samples shall
permit evaluation of the significant variations of the switch as shown on the drawings for which first article approval is
sought. The switch arrangements specified in 4.3.1.1 have been selected to provide for the known variations. First
article approval of the switches submitted will include qualification of any variation of switch as shown on the
4.3.1.1 Test samples. Test samples shall consist of the following listed switch samples. The electrical circuit
arrangement shall provide for a sufficient number of contacts to comply with the monitoring requirements of the shock
and vibration tests and the electrical loading requirements for the overload and endurance tests. If a sufficient number
of contacts are not available in the required number of sample switches, additional switches shall be used so the total
number of contacts required are provided.
Switch sample 1:
(a) Maximum number of switching decks for which approval is sought. (If rear support is specified, switch sample
1A shall have the rear support. An additional switch 1B shall be provided having the maximum number of
switching decks suitable for use without rear support.)
(b) Detent action or push-pull. (If switch design provides for both options, sample 1A shall have detent operation
and sample 1B shall have push-pull operation.)
(c) Maximum number of switch positions (angular throw).
(d) Oval handle (for detent action), level handle (for push-pull).
(e) A minimum of 6 closed contacts and 4 open contacts, including shorting and nonshorting contacts.
Switch sample 2:
(a) Maximum number of switching decks (see sample 1, item (a)).
(b) Momentary action.
(c) Maximum number of positions (for momentary action).
(d) Pistol grip or level handle.
(e) A minimum of 6 closed contacts and 4 open contacts, including both shorting and nonshorting contacts.
Switch samples 3, 7 and 8:
Same as switch sample 1, except contacts as required.
Switch sample 4:
Same as switch sample 1, except minimum number of positions and contacts as require3d.
Switch sample 5:
Same as switch sample 2.
Switch sample 6:
Same as switch sample 2, except minimum number of positions and contacts as required.
