Your magnetic switch looks interesting. How close does the magnet need to get to the grip before the switch closes? Do electic scooters have a hydraulic pressure switch on the brakes?

I used a little glass reed switch and a neodymium disc magnet about 10x1mm. It switches at about 1cm distance. You need to experiment a bit to find the ideal position for greatest distance. The cranked levers are best because the middle comes closer to the grip.

Most motorbikes/scooters use a micro-switch in the lever, but cars use a hydraulic switch, so you could use one of them. You'd need to make adapters and T into the brake line, which is a little complicated.

Kudos have hydraulic brakes with cutout switches fitted on some of their bikes. They might supply you a set if they have stock spare.

We've settled upon Hygia hydraulic brakes, mainly because of the robust, contact-less switch used. The set adds £149 to the price of a Sport or Classic bike and we will be selling the kits to upgrade earlier models, or even to non-Juicy Bike owners, may God have mercy upon them!

We sell them for £16 a pair when bought with one of our hubkits.
They come in two types: 3-pin with yellow plug and 2-pin with red plug.

You can find them on ebay too.

If you only need the cheap bit, go with Woosh.
But if you need the whole kit ours is a complete set of Tektro (rotors, calipers, pre-filled tubes and brake levers complete.
But as our spares prices aren't designed to be an income stream we only supply those to Juicy owners.
Do you specifically want a Hygia part? I can dig out some Hygia parts for you, happily.

Thankyou both for your response. I have ended up getting a full Tektro break kit with built in cut out switch. Thanks for responding. Sorry i didn't buy direct from you
