What is kill switch?
A kill switch functions as a critical safety mechanism that instantly cuts power to the eFoil motor. When triggered by a fall or manually pressed, it prevents the board from becoming a runaway projectile, eliminates the risk of injury from a spinning propeller, and stops the board from drifting away from the rider.
Efoils generally utilize three main kill switch methods:
Tether/Leash Switch: A physical lanyard connects a magnetic or physical plug from the eFoil remote or battery to your wrist or personal flotation device (PFD). If you fall, the cord pulls the plug, instantly stopping the motor.
Water-Submersion Sensor: Many modern remotes use contacts that automatically detect when the controller is submerged in water, cutting the throttle signal so the board stops immediately if you let go.
Gyro/Auto-Shutoff: Some boards use internal gyroscopic sensors that detect an abnormal angle or aggressive, sudden movement (like crashing), causing the system to power down.
Maytech Kill Switch MTSS1905WF is the first kind, with leash connects to the switch where connect with receiver and ESCs, when rider falls off from board, the leash will be disconnected from the switch and cut off 5V power and stop your board.
This time we have updated the switch with 3 channels independent PWM communication cutoff:
Supports independent PWM communication cutoff for 3 channels, which means can simultaneously cut off max 3 motor and ESCs.
If you need to use 2 or 3 motor and ESCs, this kill switch is good option for you, only need 1pcs kill switch.
When work with the MTSKR1905WF Remote and Maytech MTSF-WP32 ESCs/VESCs, TX and RX chips can be directly plugged into this PCB for real-time data transmission, eliminating the need for soldering additional wires.
