Test procedure on lamp load at atmospheric pressure:
Test procedure on lamp load at atmospheric pressure shall be as follows:
a. Test potential and load. One pole on each eight switches to be tested, four at atmospheric
and four at reduced barometric pressure, shall be energized by the specified lamp load. A
common terminal and one selected terminal shall be arranged to be "on" once per cycle.
Adjacent terminals shall not be energized. Suitable means shall be provided to indicate
when contact have failed to make and break.
b. Cycling and cycle rate. Ten cycles per minute. At the option of the supplier, cycling may be
interrupted, periodically, after each 5,000 cycles of operation.
Ordering data: Acquisition documents should specify the following:
a. Title, number, and date of this specification sheet, and the military Part or Identifying Number
(PIN) as listed in table III, example A, or tables IV, V, and VI, example B.
b. For switches not listed in table III, acquisition shall be in accordance with the ordering data of
MIL-S-3786 (for switches covered by specification sheets).
Military PIN: The PIN shall be assigned by using example A, which consists of a dash number from
table III. If the desired characteristics are not defined, the PIN shall be assigned by using the code
letters from tables IV, V, and VI as described in example B illustrated below:
Example A: Non-flux sealed switches:
M3786/35- 001 T
G
L
Switching characteristics (see table III)
Add the letter "T" when a slotted shaft is required
Add the letter "G" if positive shaft grounding is required
Add the letter "L" for low level requirement
PIN M3786/35-001TGL identifies a nonflux-sealed rotary switch of construction style F, 30° angle of throw,
one pole per deck, 2 through 12 positions per pole, adjustable stops, solder lug termination, nonshorting
switching characteristics, slotted shaft with low level capabilities and a grounded shaft.
