PROBLEM TO BE SOLVED: To provide a push button switch using a reed switch that can be configured to be thinned as a whole.SOLUTION: A plate sprint press bar 31 is provided to a flange 3 for restricting movement of a push button 2. A leaf spring 4 is fixed at the base end side 42a thereof by tables 11 and 12, and comes into contact with a bar 31 at a place 42d near to the base end side 42a. The tip side 42b is set as a magnetic shield plate 41, and the magnetic shield plate 41 is made to get in and out of the gap between the reed switch 6 and a magnet 5 by operating the push button 2, thereby turning on/off an internal contact of the reed switch 6. The push button 2, the reed switch 6 and the magnet 5 are aligned with one another. The movement of the magnetic shield plate 41 is increased, and the stroke of the push button 2 is reduced. As a result, a push button switch having a thin shape can be implemented. |
