This 8 position rotary switch can be utilized to control boost levels, traction control settings, map switching, or any other analog input on your standalone ECU. This switch is compatible with any standalone that has analog inputs including ECUMaster EMU, AEM, Haltech, Holley, and many other standalone ECUs.
The rotary switch uses a high quality Alps switch, comes with an aluminum knob, and is assembled in the USA!
The pinout is very simple, only requiring a voltage input (Vin), Ground (GND) and the output signal (OUT). The rotary switch can take up to 24v input voltage, but it is recommended to use a stable voltage signal like a 5v reference for other sensors, and not main 12v power connected to the battery/alternator.
The switch includes a washer and nut for mounting behind a panel, however each installation is different, and you may need to add spacers or washers to flush mount it to a panel. The mounting thread on the rotary switch is M9x0.75.
Example output voltages are listed below by input voltage, and rotary switch position.
