The forklift neutral safety switch is an important safety protection device on the internal combustion forklift. If the failure of its protection function is not discovered in time, when the driver starts the engine in gear and does not step on the brake pedal, the forklift will suddenly accelerate and run, which may cause serious safety accidents. Familiar with the action principle of forklift neutral safety switch, understand its common faults, and strengthen relevant inspections can effectively prevent accidents caused by internal combustion forklifts due to the failure of neutral protection.
1) The forklift neutral safety switch light is always on. The reason for this kind of fault is that the internal contacts are always in contact. Due to the high temperature generated by the arc discharge, the contacts are ablated and the plastic parts are melted and broken, resulting in the contacts not being able to be disconnected normally. , the switch is always in the normally on state.
2) The forklift neutral safety switch does not light up. The reason for this failure is that the internal contacts are always in an open state. Due to the poor sealing of the switch, the springs and lugs inside the switch are corroded, causing the contacts to fail to conduct. The neutral switch indicator light does not come on.
3) The indicator light of the forklift neutral safety switch is on and off when it is on. It may be due to poor contact of the internal contacts of the switch, or the gap between the contacts and the guide block is too large when the switch is assembled, causing the switch to be intermittent and the switch contacts to be abnormal. Contact.
