Abstract

The present invention provides such a structure that a male-type terminal which in inserted to a female-type terminal to come in contact therewith comprises a resistor on at least a tip portion of a resistor and that at the time of insertion to the female-type terminal, a switching is made from the resistor to the conductor portion and, at the time of detachment from the female-type terminal, switching is made from the conductor portion to the resistor.

Claims
