ROLAIR 458003-E Manual Reset Push Button

Makita 458003-E Overload Switch (manual reset push button) is an authentic replacement part for Makita MAC5200, MAC2400, and MAC700 air compressors. This 458003-E device acts as a thermal overload protector that interrupts motor current when the compressor draws excessive current, and it requires a manual reset to resume operation after tripping. Used to replace worn or failed overload switches in these Makita models, it is commonly cited as the direct replacement part for MAC5200, MAC2400, and MAC700 units. The assembly is specified as a 20 amp manual reset design to handle typical high‑current motor circuits in these compressors. For service, power should be disconnected and the switch wired in accordance with Makita’s repair instructions, with secure mounting and correct terminal connections during installation. This part is a standard, widely available replacement from retailers and service providers serving MAC5200, MAC2400, and MAC700 owners and technicians performing routine maintenance or fault repair.
