PROBLEM TO BE SOLVED: To attain the force for bringing a moving contact into contact with a fixed contact without requiring a separate spring and reduce the cost by providing elastic pieces integrally formed on a contact holder and exciting the moving contact toward the fixed contact. SOLUTION: Two elastic pieces 28 are integrally formed on the lower face side of a second contact holder 14. These two elastic pieces 28 are extended from the front and the rear in the opposite directions, they can be vertically deflection-deformed from base sections by notch sections 29 formed on the peripheries except the base sections, and projections 30 are provided on the lower faces of tip sections. A moving contact 13 is assembled to the holder 14 while thrusting the projections 30 of the elastic pieces 28 and the whole elastic pieces 28 with a bottom section and inserting both side sections into both vertical grooves 26 and fitting projections 27 into oblong holes 31. The force for ringing the moving contact 13 into contact with a fixed contact can be obtained by the elastic pieces 28.
