Patent ID: 7982577

Claim:
A safety device for a switch, comprising: a first terminal; a second terminal, a first contact point connected to an end of the second terminal; a conductive plate having a first end fixed to the first terminal and a second contact point connected to a second end of the conductive plate, the second contact point located corresponding to the first contact point; and a push rod located between the first and the second terminals, the push rod located at a side of the conductive plate and a gap defined between a distal end of the push rod and the conductive plate when the first contact point contacts the second contact point, wherein under a current overload condition, the conductive plate is bent and deformed to move the second contact point away from the first contact point, a mediate portion of the conductive plate is bent downward to contact with the end of the push rod and the push rod applies a force to the conductive plate which is moved in a direction away from the first contact point.
