SSY007202990 Switch to Power Relay Wiring Harness Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

This product connects the power switch and the intermediate relay, transmitting control signals and operating current to ensure rapid switch response and stable circuit conduction. It eliminates signal delay, power supply fluctuations, and relay malfunctions, making it suitable for harsh working conditions such as bumpy construction sites, large temperature differences, and oily and dusty environments.
With precise original factory specifications and hole positions, it supports direct replacement in place without wire cutting. It uses a high-purity copper core with an oil-resistant and flame-retardant sheath, offering stable current carrying capacity, low heat loss, and tensile strength insulation, making it suitable for complex engine bay conditions. Old wiring harnesses are prone to oxidation and cracking, and loose connections, leading to signal failure, relay malfunctions, intermittent power outages, and other faults. Suitable for electrical control maintenance, circuit overhaul, and bulk stocking, it ensures stable operation of electrical control circuits.
