ABSTRACT:
An electronic switch is disclosed using a piezoelectric push button transducer and an electronic switching circuit. The push button piezoelectric transducer is connected with the switching circuit with a polarity to provide a switching voltage in response to actuation of the push button switch by finger pressure. The connection is such that the polarity of the voltage generated as a result of differential thermal expansion of the piezoelectric transducer is opposite that produced by finger pressure on the push button switch and does not produce false switching from fast temperature rise. In order to protect against false switching due to high temperature soak of the electronic switch, a thermistor is provided in the electronic switching circuit.
