The invention discloses an aircraft parking brake switch, belonging to the technical field of aircraft parking brake. The aircraft parking brake switch comprises a box body and valve core assemblies, wherein a camshaft is arranged in the box body; a plurality of valve core assemblies are arranged on one side of the camshaft along the axial direction of the camshaft; the top end of each valve core assembly is contacted with the camshaft; an output nozzle or a spring seat is arranged at the tail end of each valve core assembly; the valve core assembly provided with the output nozzle is communicated with the valve core assembly provided with the spring seat by virtue of an oil duct; an input nozzle is arranged on the other side of the camshaft along the axial direction of the camshaft; the top end of the input nozzle is contacted with the camshaft; a temperature compensation mechanism is arranged on one side of the input nozzle; the temperature compensation mechanism is communicated with the valve core assembly provided with the output nozzle by virtue of a hydraulic channel. According to the technical scheme, due to the temperature compensation mechanism, the influence of temperature change on the braking pressure is overcome, so that the braking pressure change is extremely small, the braking pressure is kept stable, each hydraulic element is prevented from being damaged, and the aircraft braking safety is guaranteed.
