Voltage Breakdown:
500 Vac between mutually
insulated parts.
Life Expectancy:
10,000 cycles at 200 milliamps.
One cycle is 360° rotation and a return through all
switch positions to the starting position.
Low Level Rating:
Make and break a 50 mV, 1
milliamp, resistive load for 10,000 cycles with a
maximum contact resistance of 50 milliohms.
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.

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.

Mounting Hardware for Style BF or BP:
One
mounting nut .062" thick by .312" across flats
and one external tooth lockwasher supplied
with each switch. Mounting nut is brass,
cadmium-plated and lockwasher is spring steel,
cadmium-plated.
