PURPOSE:To provide a push switch for a printed circuit board, having the capability of connecting and separating electrical circuits to and from each other by constituting the push switch in such a way that an extremely small switch body containing a contact spring piece is mounted at the intended position of the printed circuit board, similar to the case of various types of small electronic parts. CONSTITUTION:A contact spring piece A comprising a pusher 5, a fulcrum shaft 6, and upper and lower contact pieces 3a and 3b is provided, while a case B having a slit 8 on a top plate, shaft holes 9 through right and left side plates and grip means 10 on a lower end is provided. The contact spring piece A is housed in the case B with the shaft 6 coupled to the hole 9 or a recess, and the pusher 5 inserted in the slit 8, while the upper end of the pusher 5 being projected above the top plate for mounting a switch body S. This switch body S is mounted on the circuit 11 of a printed circuit board P via the mounting means 10. Thus, the lower contact piece 3b of the contact spring piece A is pressed for contact with one section of the circuit 11, and the upper contact piece 3a thereof is positioned above the other section of the circuit 11. |
