Rotary Switches
One cycle is 360° rotation and a return through
all switch positions to the starting position. The
data for the curve was measured at sea level,
25°C and 68% relative humidity with the
following limiting criteria:
Contact Resistance: 50 milliohms maximum
(15 milliohms initially).
Insulation Resistance: 10,000 Mohms
minimum between mutually insulated parts.
Contact Grayhill for information if the life limiting
criteria is more critical than those listed, if the
required cycles of operation are greater than
those listed, if a larger make and break current is
required than the one listed for the desired number
of cycles, or if elevated temperatures or reduced
pressures are part of the operating environment.
