<P>PROBLEM TO BE SOLVED: To improve versatility by achieving on/off switching and detection of push-in amount with the same structure. <P>SOLUTION: A signal processing circuit 6 can generate an analog voltage signal corresponding to the inductance of a detection coil 42 which changes depending on the distance between the detection coil 42 and a movable body 50, detect push-in amount of a press button 1, and output an operation signal having a level corresponding to the push-in amount. Alternatively, it can output an on/off operation signal by comparing the push-in amount with a threshold xth. Excellent durability is attained because there is no mechanical contact, and versatility is improved because on/off switching and detection of push-in amount can be achieved with the same structure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
