う問題があった。2. Description of the Related Art Conventionally, when a movable contact comes into contact with a fixed contact, a push button switch for giving a click feeling in order to detect this state is used when a reversing spring is pushed down by a handle to invert it. It is designed to give a quick feeling. As described above, in the push button switch using the reversing spring, the contact characteristics of the contacts and the conditions such as the spring stress of the reversing spring are complicatedly related, and depending on these conditions, the reversing load acting as the pressing force on the reversing spring and its reversing Since the reversing characteristics of the reversing spring such as the position have been determined, there is a problem that the reversing characteristics suitable for a plurality of operators cannot be obtained.

The reversing characteristics of the reversing spring can be set without limitation, and a flexure spring such as a leaf spring can be adopted for the contact portion, so that a sufficient contact pressure and rolling amount can be secured. The movable contact can be rubbed against the fixed contact to prevent improper energization of the contact, and when the contact comes into contact with or separates from the contact, the reversing spring can give a click feeling to accurately determine the on / off state of the contact. It is an object of the present invention to provide an instant return type push button switch that can be checked in advance.
