Application:
ZJK125A series emergency power-off switch adopts mechanical limit design and uses red mushroom head handle to control the switch on and off. The product design is compact and reliable. It is widely used in battery vehicles, electric forklifts, electric vehicles, excavators and other DC. The power system is used to disconnect the power supply in an emergency to prevent accidents from spreading and spreading.
