5985-99-075-6036 5985990756036 990756036 is a device for reducing the strength of an alternating current signal either continuously or in steps, without causing appreciable signal distortion, by maintaining substantially constant output and/or input impedance match. continuously variable resistive devices must consist of at least two sections or one section with at least two rotating contacts. the item must have an overall attenuation rating. includes tandem mounted variable resistors designed to function as an attenuator but whose terminals are not connected. see also resistor, vaiable (as modified).

5930-12-144-1555 5930121441555 121441555 is a switch that is externally actuated by a device such as a push rod or button, which requires pushing for each actuation. the action may be momentary, with mechanical return. the actuating device may or may not be an integral part of the switch. the item may include provisions for mounting indicating lamp(s) or light emitting diode(s) in the actuator. includes items consisting of individually separable switches that are physically interlocked, that have a common actuator, or are electrically connected. excludes light-switch; light-switch assembly; switch, beam selecting, headlight; switch, foot; switch, interlock; switch, pressure; switch, push-pull; switch, sensitive and switch assembly. for devices which start, stop, reverse, select and/or regulate the speed of a motor, see starter, motor and controller, motor.

5331-01-686-3447 5331016863447 016863447 is a nonmetallic circular item with an aperature, having a solid round cross-section. they are used primarily for sealing. for items with other than round cross section, see packing,preformed. for noncircular items with a round cross-section, see seal,nonmetallic round section and rubber,round section.
