Im using a piezo switch to activate a simple single transistor latching circuit that locks in a mosfet and Im having a bouncing problem of sorts. Pressing the switch fires corectly and activates or deactivates the mosfet as intended but if the piezo is subjected to vibration or bumps over time the circuit will reverse its state. What I'm guessing is the problem is that vibrations are charging the cap in small busts that lead up to the circuit opening or closing.
It my searches it seems that a 555 circuit might be the answer.
Can anybody point me in the right direction as to what may help aleaviate this problem? If there is not a circuit that already takes care of this I thought that if a one shot circuit that discharged the cap when when the button is not depressed would make it work. The one shot could send the clean signal to the latching circuit. Am I in the right ballpark?
Thanks
