ABSTRACT:
In a switch apparatus having a membrane structure, when it is detected that a conductive pattern comes into contact with both of two conductive patterns, it is judged that a normal ON operation is performed, and an ON signal is output. When the conductive pattern comes into contact with only one of the two conductive patterns, it is judged that a failure such as a short-circuit due to peeling occurs, and an alarm signal is output. The switch apparatus has a self-detecting function, so that it reliably detects an unstable condition of a failure such as a short-circuit due to peeling.
