Variable capacitance push-button switch |
摘要 |
In a capacitive-type switch having two capacitive levels, a relatively thin blade of a desired dielectric material is interposed between two capacitive plates by downward actuation of a push-button switch so that the plates become separated by the blade. When the push button is released, the blade is removed from between the two capacitive plates and a high capacitance level is once again achieved.
