• Specification

• Function

Control of Heater Circuit: It serves as a heater switch in Komatsu equipment. When the start switch is set to the preheating position, the control circuit of the relay switch operates, generating an electromagnetic force that closes the relay switch. Subsequently, a large current from the battery passes through the relay switch to the heater, which heats the air at the intake manifold inlet, improving the engine's starting performance.
