The RaceGrade Two Channel switch is a multipurpose device
that receives two high side inputs to control a single switched grounding
output. The inputs are isolated from each other to prevent cross-feeding of the
two independent activation circuits. The device works as an OR circuit so
either high side input will trigger the switch output to ground. The current
capacity of the output is suitable to drive a relay or digital input on an ECU.
Do not connect this device directly to load requiring current more than 270mA.
