This ignition switch is engineered to meet standardized specifications for excavator electrical system operation, ideal for high-frequency use in construction and mining sites where equipment reliability is critical. The housing adopts reinforced high-temperature resistant engineering plastic, which can maintain stable performance in working environments with temperature ranges from -40°C to 85°C, effectively avoiding circuit failure caused by vibration and dust intrusion during long-term equipment operation. The internal contact components are made of wear-resistant copper alloy, ensuring consistent electrical conductivity after tens of thousands of rotations, supporting stable start-up and power supply control for the excavator's core electrical components. It matches the original installation position directly, no additional modification is required during replacement, effectively reducing equipment downtime. This component is manufactured according to factory standard parameters, with consistent interface dimensions as the original installed part, ensuring seamless matching with the excavator's electrical system.
- Reinforced high-temperature resistant engineering plastic housing, with strong vibration and impact resistance, suitable for harsh construction site operation environments
