SWITCHING DEVICE

A LOCKING CUTOUT (6C) ALLOWING A FIRST LOCKITIG PROJECTION (3A) OF A COMMON TERMINAL (3) TO PASS THERETHROUGH AND ONE END FACE (6D) THEREOF BEING ABUTTABLE AGAINST THE LOCKING PROJECTION (3A) IS OPENED IN A PLATE SPRING (6). THE END FACE (6D) OF THE LOCKING CUTOUT (6C) IS ABUTTED AGAINST THE FIRST LOCKING PROJECTION (3A) IMMEDIATELY AFTER A MOVING CONTACT ( 4A) HAS COME INTO CONTACT WITH A FIXED CONTACT (2A), SO AS TO CONTROL A POSITION OF THE PLATE SPRING (6). THIS STRUCTURE PROVIDES A SWITCHING DEVICE WHICH DOES NOT EXERT BAD INFLUENCE ON THE LIFE THEREOF AS USED UNDER ELECTRICALLY LOADED STATE EVEN WHEN A SPEED FOR PUSHING-IN IS FAST, AND WHICH IS READY FOR VARIOUS KINDS OF LONG AND SHORT STROKES WITH THE SAME CONTACT STRUCTURE, BY STOPPING SELF-MOVING OF THE QUICK-ACTING MECHANISM WITH ABUTTING A MEMBER OTHER THAN THE SLIDING MEMBER WHILE TAKING CARE NOT TO CAUSE A LARGE BOUNCE FOR SEPARATING CONTACTS.(FIGURE 1)
