DETAIL SPECIFICATION
SWITCHES, ROTARY (CIRCUIT SELECTOR, LOW-CURRENT CAPACITY),
GENERAL SPECIFICATION FOR
This specification is approved for use by all Departments and Agencies of the Department of Defense.
1. SCOPE
1.1 Scope
. This specification covers the general requirements for circuit selector, rotary switches,
designed for low power, alternating current (ac) or direct current (dc) switching applications (capable of
making and breaking a resistive load of 2 amperes or less, unless otherwise specified (see 3.1
), which
are primarily for use in electronic and communications equipment. Acquisition of switches of a design
covered by a specification sheet will require additional data as specified in 6.2.2
. Acquisition of switches
of a design not covered by a specification sheet will require additional data, giving detailed electrical and
mechanical requirements, tolerances, and applicable additions and exceptions to the general
requirements and tests specified herein (see 6.2.3
). Switches which differ because of electrical
configuration, shape, or size of operating shaft, type of construction, number of switch sections (see
6.7.6), (see 3.2), bushing length, temperature life characteristics, angle of throw, vibration grade, shock
type, insulation, or altitude are considered to be standard switches under a particular style (see 3.2),
provided they meet the envelope size and dimensional, environmental, and electrical requirements of the
particular style.
1.2 Classification
.
1.2.1 Military Part or Identifying Number (PIN). The term Part or Identifying Number (PIN) is equivalent
to the term part number which was previously used in this specification. The military PIN (when
applicable) will consist of the letter "M", the basic number of the specification sheet, and an assigned
dash number (see 3.1
). The dash number will be either sequentially-assigned or coded, as shown in the
following examples:
M
3786/XX -0001
I I I

number dash number
OR
