Rotary Switches Special Function Rotary Switches SERIES 09, 42, 44, 50, 51 Isolated Position FEATURES Protected Switch Positions For Safety, Calibration, or Stand-by Choice of Push- or Pull-To-Turn 1 /2 Diameter, 200 mA and 1 Diameter, 1 Amp Switch 10,000 Cycles of Operation DESCRIPTION An isolated position is one which cannot be reached by the normal rotation. An additional action is required by the operator. It could be either Push-To-Turn, or Pull-To-Turn. After the switch is rotated to the isolated position, releasing the shaft locks the switch in that position. Push or pull again to rotate the switch again. Use isolated positions to protect a switch position from indiscriminate rotation. Such safety positions might include calibrate, off and/or stand-by.
