PROBLEM TO BE SOLVED: To provide a pushing switch capable of obtaining sufficient resilient push-up force for a keytop in a simple structure and at the least number of components and smoothly moving up and down the keytop. SOLUTION: The pushing switch comprises a flexible switch base plate 110, and the keytop 70 installed on a pair of upper and lower switch contacts 123 and 127 (membrane switch M) prepared on the flexible switch base plate 110 and turning on and off the membrane switch M. A keytop installing section 117 and resilient section 119 are arranged on the flexible switch base plate 110. A base plate folding section 135 is formed by installing the keytop installing section 117 on the keytop 70 while folding the keytop installing section 117, and the keytop 70 is rebounded by the base plate folding section 135 in the direction separating from the flexible switch base plate 110. The resilient section 119 also makes the keytop 70 rebound in the direction separated from the flexible switch base plate 110 in a folding state. COPYRIGHT: (C)2008,JPO&INPIT
