MIL-S-3786F, MILITARY SPECIFICATION: SWITCHES, ROTARY (CIRCUIT SELECTOR, LOW-CURRENT CAPACITY), GENERAL SPECIFICATION FOR (6 JAN 2006) [S/S BY MIL-DTL-3786G]., 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 ofmaking and breaking a resistive load of 2 amperes or less, unless otherwise specified (see 3.1), whichare primarily for use in electronic and communications equipment. Acquisition of switches of a designcovered by a specification sheet will require additional data as specified in 6.2.2. Acquisition of switchesof a design not covered by a specification sheet will require additional data, giving detailed electrical andmechanical requirements, tolerances, and applicable additions and exceptions to the generalrequirements and tests specified herein (see 6.2.3). Switches which differ because of electricalconfiguration, shape, or size of operating shaft, type of construction, number of switch sections (see6.7.6), (see 3.2), bushing length, temperature life characteristics, angle of throw, vibration grade, shocktype, 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 theparticular style.
