just another thought as i have still 3 swiches over in the 4066
i am not sure if i can leave the sensor line to the VSD floating so i could short it with another swich(4066) to the 0V still there is the risk (as both swiches are swiched simultanuasly still there could be a time differance) that there is a direct short from the buffer amp to 0V
i could put a resistor in that line (10 k
hm: ) to the 0V to limit the max curent in a case of a shorting
or is this over worried from my side ??
