PROBLEM TO BE SOLVED: To eliminate a scraping abrasion of an contact piece driving insulator generated when a plug is inserted into and pulled out from a plug insertion hole. SOLUTION: A plug insertion hole 2 is opened at the front part of a body 1, and the contact piece driving insulator 10 is arranged at the peripheral part of the plug insertion hole along the longitudinal direction thereof, and a metal piece 11 is adhered and fixed to the front surface part of a main body made of insulating plastics, namely, to the surface facing the plug insertion hole 2. A movable contact piece 5, and a fixed contact piece contacting with the movable contact piece in a steady-state, driven by the contact piece driving insulator 10, are arranged at the back side thereof. The other movable contact piece 7 having a protrusively curved vertically moving part 7a, and the other fixed contact piece contacting with the other movable contact piece in a steady- state are arranged at the peripheral side of the plug insertion hole 2 facing the contact piece driving insulator.
