Multidirectional switch and complex type switch using the same

摘要

A switch substrate 11 is provided on the upper surface with a pluralities of fixed contact points 11A, 11B, and a driving body 12 made of an elastic material is placed over the switch substrate 11. The driving body 12 is integrally formed of a center press portion 14 and a periphery press portion 17 corresponding respectively to the fixed contact points 11A and 11B. The periphery press portion 17 is provided on the bottom surface at the central end region with a first protrusion 18, the cross sectional end shape of which protrusion being round and making contact to the switch substrate 11. The first protrusion 18 works as a fulcrum separating the functions of center press portion 14 and periphery press portion 17 to be independent to each other. As a result, even when an operating force is given on the operating body 22 at a place somewhat deviating from a right targeted area, the operating force can surely bring only a targeted switch into ON - OFF operation.
