●The 142503020012A (Model SY485C1I4KH5.1.32 / SY036GCB60788) Knob Switch ( Поворотный переключатель / Регулятор оборотов / Interruptor de perilla) is an electronic diesel engine throttle potentiometer switch engineered for SANY heavy hydraulic excavators.
●Material number 142503020012A is mounted on the operator cabin right electrical installation plate (such as the 14486199 electrical equipment plate and side console) adjacent to the one-key start switch (142599000099A) and switch panel (142505000006A). It enables the operator to adjust diesel engine RPM across stepped or continuous working modes (Eco, Standard, Heavy Duty, and Trenching). By converting physical rotary dial position into precise analog electrical resistance/voltage signals sent directly to the machine multi-controller (ECU/PLC), it regulates fuel injection rates and hydraulic pump displacement, ensuring optimal power delivery, rapid transient response, and fuel efficiency.
●Verify dial rotation angles, internal potentiometer resistance curve, connector pinout (harness plug keying), and console bracket mounting dimensions prior to order confirmation.
●Mounting Position: Operator Cabin Electrical Installation Plate / Side Console
●System Application: Excavator diesel engine throttle speed governing, ECU command input, and fuel economy control
