Hall Sensor magnetic power TOGGLE/Latching switch

Perfect solution to build a water proof switch:

- Dive Lights
- Bike Lights
- Outdoor lights

Halltg Power Toggle Switch :

Solid State Hall Sensor input.
Operates from 3V to 25V.
Can switch (low side n-chan power FET) up to 15A.
Can be used as a momentary action switch for any TaskLED "flex" driver (e.g. maxflex, h6flex etc).
Very low on resistance (typically 6 milliohms).
Very low quiescent current (typically 60uA in the presense of a magnet and 30uA when not), less than 0.05 amp.hour per month drain).
Compact size (0.60" x 0.50"). Maximum thickness 0.115".
Can be mounted with supplied thermal adhesive tape to the inside of a metal housing (non-magnetic).
Protected against reverse polarity connection

Hall Sensors are solid state devices that sense a magnetic field. The Hall Sensor and associated circuitry on the Halltg board provides a toggle/latching switch action. Apply a magnetic field (small magnet) of sufficient strength and the and the power FET will toggle on, remove the magnetic field and the power FET will remain on. Re-apply the magnetic field and the power FET will toggle off.

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