Heated gloves are amazing. Soothing to arthritis, they can make bitter cold winter days tolerable.

The main reason I suspect they are not more popular is the annoying matter of keeping them charged. It’s really easy to forget to turn them off.

What if the glove could detect if there was hand present?

* What if they turn off if you clip them together?
* What if you make a fist and squeeze and that turns them on for 5 min?
* How else could they detect when to be on/off?

I was surprised to find out that heated mittens go back to at least the 70s. I wonder if there are even older inventions along these lines.

"Unsnap elastic band when heating action is no longer needed."

We have been dreaming of this for half a century.

Red knit mittens with a small leather battery pocket. They sit next to the box they were sold in, classic 70s graphic design "Lectra-Mits" The text on the back of the box. For real cold weather comfort ... keep your hands warm with Lectra-Mits IMPORTANT• Use only with Alkaline s D-Cell Batteries EASY DIRECTIONS Insert Alkaline D-Cell Battery upside down (Drawing A.) Ordinary "Flashlight Batteries" will not work satisfactorily. To start heating action close snap at end of elastic band BATTERIES Lectra-Mits are designed to be used with D-CELL ALKALINE BATTERIES (Eveready E-95 or equivalent). These are available in most drug and hardware stores and in all photo-supply stores. The Alkaline D-Cell battery lasts about 4 hours if used continuously, much longer if used intermittently. (Ordinary"flashlight batteries" provide less heat, last less than 1 hr.) In extreme cold, carry batteries in an inside pocket when not in use. LAUNDERING Wash in luke-warm water with plenty of rich suds. Do not agitate violently. Use gentle squeezing action. Don't stretch or wring out so hard as to loosen electrical connections.

Does anyone know of a highly durable and reliable clip like this “side release buckle” that is also an electric switch?

I see the wires connecting such a switch as another possible point of failure. So maybe it would be better to not have wires. What about a latch that needs no power source and sends a signal via NFC or something when closed or opened?

A collection of black plastic side release buckles spread out in an array. These are the type of buckles that you squeeze on the side and they open having three prongs

@futurebird@sauropods.win the hovding inflating bike helmet used the metal closing snap as the arming switch to turn itself on.
