5996-21-921-1817 5996219211817 219211817 is an electronic device whose radio frequency input signals control power from a source independent of the input signals, and delivers radio frequency output signals of greater amplitude with respect to current and/or voltage. the output signals characteristics are uniformly related to the input signals. it operates at frequencies above 20 kilohertz.

4720-14-263-4664 4720142634664 142634664 is a length of nonmetallic hose with fittings on one or both ends. for items without fittings, see hose, nonmetallic. excludes hose assembly, air duct; and hose assembly, air duct, air breathing.

5925-14-557-1761 5925145571761 145571761 is a device with means other than fuses for automatically opening the circuit in which it is installed when the current varies from the predetermined value for which the device is set. may include provisions for manual operation. at least one set of contacts must be in series with the actuating element(s). a combination of semiconductor and passive devices may be used in lieu of contacts. for automatically operated items in which the actuating (tripping) element and contacts are not in series, see relay (as modified). for items which are operated both manually and automatically but the actuating elements and contact are not in series, see relay-switch. excludes circuit breaker box and magneto "breaker" assemblies. see also switch (as modified); and controller.

5930-01-487-2485 5930014872485 014872485 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.
