PROBLEM TO BE SOLVED: To provide a structure of a push button switch constituted as a thin push button switch with an insulated substrate as a base and where solder spreading to the conductive pattern can be prevented even when in reflow soldering. SOLUTION: In the device, a multiple number of connecting terminals 1f and 1g formed on side end parts of the rectangular insulated substrate 1, a first and a second fixed contact points 1a and 1b that are connected to the connecting terminals 1f and 1g with conductive patterns 1c and 1e and formed facing each other on the surface of the insulating substrate 1, moving contact points 3 that are installed able to flip on the fixed contact points 1a and 1b and carry out conduction between fixed contact points 1a and 1b by fliping and an insulating film 2 that is pasted onto the conductive patterns 1c and 1e as well as covering the insulating substrate 1 and holding the moving contact points 3 on the insulating substrate 1 are provided. In this case, spacing parts 1h and 1j separating the conductor patterns 1c and 1e from the insulating film 2 are formed in the direction crossing between the connecting terminals 1f and 1g and each of the fixed contact points 1a and 1b in the pasting part between the conductor patterns 1c and 1e and the insulating film 2.
