LED 401

An electronic, three-wire petrol/gas switch, which performs a number of functions, from the selection and optical/acoustic signaling of the operating mode to the indication of the gas level in vehicles which have systems for fuelling the engine with alternative fuels, i.e. autogas.
One of the advantages of the switch is its attractive design and the arrangement of decorative elements which are formed as illuminated channels. Additionally, the center button can be installed in different positions at 90O intervals, in a way that allows the position of the logo to be changed according to the horizontal or vertical  installation of the switch.

Basic features and advantages of LED 401:
1.    A built-in photoresistor allowing the automatic adjustment of the backlighting level, depending on ambient light.
2.    Optional “manual” adjustment of the backlighting of the switch.
3.    Two-color illumination of the button with the logo which indicates low fuel level and operating modes.
4.    The possibility to change the direction in which the LEDs indicating the gas level  are turned off depending on the position of the installation of the switch.
5.    Integrated buzzer.
6.    Adjustment of the volume of the buzzer.
