G3 automotive plunger switch in automotive electronic parking system
G3 plunger micro switch is designed for automotive electronic parking brake system (EPB) as a key signal input component and is installed in the operating mechanism. When the driver presses the EPB button, the plunger switch quickly recognizes the mechanical action and converts it into a stable electrical signal, which is transmitted to the vehicle electronic control unit (ECU).
