Piezotg Power Toggle Switch:

• Interface pins to connect to a user supplied Piezo switch.
• Operates from 3V to 25V.
• Can switch (low side n-chan power FET) up to 15A.
• Very low on resistance (typically 6 milliohms).
• Very low quiescent current (typically 20uA standby), less than 0.05 amp.hour per month drain).
• Compact size (0.65" x 0.50"). Maximum thickness 0.115".
• Can be mounted with supplied thermal adhesive tape to the inside of a metal housing.
• Protected against reverse polarity connection

Piezo Switches are solid state devices that produce a voltage when pressure is applied. This voltage activates circuitry inside the piezo switch that causes the 'output' to momentarily conduct, emulating a momentary action switch.

A user supplied Piezo switch and associated circuitry on the Piezotg board provides a toggle/latching switch action. Pressing the Piezo switch will cause the power FET on the Piezotg board to toggle on, pressing the Piezo switch again and the power FET will remain toggle off. Circuitry ensures that the Piezotg will always power up with the output off.

Note: the Piezotg is NOT waterproof, it needs to be installed in a waterproof housing, potted or coated in a waterproof sealant.
