Abstract

A programmable push button having a microcontroller located therewithin to provide a switching signal to operate an electronic switch and thereby enable power to be supplied from a source of power to a load to initiate an external event. The push button also has a piezoelectric assembly which is responsive to one or a sequence of manually applied pushing forces at a push button cap. The microcontroller is interconnected with the piezoelectric assembly on a printed circuit board so that output voltage signals generated by the piezoelectric assembly are applied to the microcontroller as a series of digital pulses. The microcontroller can be programmed by applying a particular sequence of pushing forces to the push button cap so that one or more times can be set during which the external event will be initiated or to require a predetermined security code to be entered before the external event can be initiated.
