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.
