Basic Wiring with Dual Battery Setup
Obrazek TU
Optional Mechanical/Electronic Switch
The KSW18 allows a combination of two signal inputs to improve operational safety. By default, only the primary input (Rx line) is used. For additional safety (e.g., preventing accidental engine ignition activation), use both primary and secondary inputs.

- Place the touch button anywhere on your model on the surface made of nonconductive material.
- Make the status LED visible from outside the fuselage.
Activation steps
- Connect the receiver battery to the KSW18 and briefly touch the button. Status LED should start blinking. If not, please increase the couch sensitivity parameter in the configuration.
- Touch and hold the button for about 2 seconds. The LED starts blinking. At this moment, release the button. The main output will be activated.
TELEMETRY AND SETTINGS
Obrazek The device is compatible with JETIBOX and you can use it for programming. The JETIBOX menu is divided into three sections:
- Actual values – Displays real-time telemetry data, including temperature readings and their respective
minimum and maximum values.
- Reset Min/Max - Resets all recorded minimum and maximum telemetry values. To reset, press
the left and right buttons simultaneously.
- Settings – provides access to core device configuration parameters.
- Language – allows the selection of the display language for the JETIBOX interface.
- Input type – defines the primary input control for the switch:
- Servo signal (default) – Uses a PWM signal from the receiver to control the switch state.
