Push button selector SPA-02K


The selector is intended for use on vehicles in various types of transmission control systems – mechanical, hydromechanical, hydrostatic, electromechanical. The selector works with other electronic devices of the vehicle via the CAN interface (J1939 protocol).

Using the lever mechanism of the selector and the “MODE” button, the driver controls the transmission:the direction of travel, operating mode and gear number (for a stepped transmission). The selector also reads and processes signals from sensors and transfers information via the CAN bus.


The selector has six buttons: D – forward movement, N – neutral, R – reverse. “+” – shift up, “-” – shift down, the “MODE” button can be used to select the transmission operating mode, for example, automatic or command. All buttons are backlit. The alphanumeric display can display the selected driving mode, or diagnostic information.
