Electric brake hall switch sensor suit Logan levers equipped models of Burn-e (typically early 2022+) and all Klima and Blast models.
This is a hall effect sensor responsible for informing the controller of the position of the brake lever which activates electric braking and brake light.
Sourced as NAMI factory spare. Will support most makes/models that adopt Logan levers.
Available in two variants to suit the older or newer Logan lever variants:
Older version: Uses a 6.2mm diameter hall switch to sense positioning. The nut is smaller and separate from the moulding.
Newer version: Has a mechanical actuator on the end to sense positioning. The nut is larger and forms part of the moulding.
Ensure you pair the appropriate switch with your lever, they are not interoperable/universal.
Adopts the common convention used amongst nearly all eScooter makes and models with a red 2-pin M8 connector being normally open (when lever is not activated the circuit is open) and closed when the lever is activated. Cable length 80mm.
Typically required as replacement when electric brake and brake lights will not apply, or will continuously or intermittently activate despite lever not being engaged and calibration will not resolve symptoms.
Notes:
Prior to removing, fitting or calibrating the position of the switch, ensure you backing off grub screw that secures the bolt's position within the lever.
It is recommended to only adjust/calibrate one switch at a time and allow to bed-in prior to adjusting the other lever. Adjusting both concurrently can make it difficult to fine tune.
Image below shows the Logan Older version switch contrasted with the similar appearance Zoom Switch for Zoom levers. Both have a 6.2mm diameter with the Zoom having a notch/key that is wider (and a little shorter).
The newer version may also suit XOD branded levers such as the levers that accompany the black NUTT A5-D calliper on early models of Dragon Cyclone.
The newer version being mechanical would not suffer interference of magnetics or harmonic distortion as much as the magnetic hall switch, which works much like a security reed switch in a door.
