  • Publication number: 20190097363
    Abstract: A protection contactor includes a contact part coming into contact with a conductor of an electric device and having elasticity and an ESD protection part connected to a portion of the contact part to extend to a circuit board disposed to be spaced apart from the contact part and comprising a conductive material. Thus, in accordance with the exemplary embodiments, current due to an overvoltage or an ESD voltage of a discharge starting voltage concentratedly flows through the protrusion to improve bypassing efficiency to a ground part. Thus, the current due to the overvoltage or the ESD voltage that is above the discharge starting voltage may be effectively bypassed to prevent an internal circuit from being damaged by static electricity.
