Electrical Ratings

Chart shown for non-shorting (break before
make) contacts, resistive load.

minimum between mutually insulated parts.
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.

Bushing:Brass,tinzincplating
Stop Pin: Stainless steel, passivated
Detent Balls: Steel, nickel-plated
Detent and Contact Springs: Tinned music

wire

Rotor Contact: Silver cad-oxide, gold-plated
Terminals and Common: Brass, gold plate

.00002" minimum thickness over silver plate
.0003" minimum.
Shaft in Style BF or BP: Zinc

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 Mo hms

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.

Materials and Finishes

Switch Base: Diallyl per MIL-M-14
Detent Cover and Detent Rotor in Styles AP,
AF, BP, and BF: Phenolic per MIL-M-14

Integral Knob and Detent Rotor in Style CF
or CP: Red Thermoplastic
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,zincplated

and lockwasher is spring steel.

Additional Characteristics

Contact Type: Non-shorting, wiping contacts
Terminals: Switches are provided with the full

circle of terminals regardless of the number of
active positions.
