One cycle is 360° rotation clockwise and 360°
return. The data for the curve was measured at
sea level, 25°C and 68% relative humidity with
the life limiting criteria which follows.
Contact Resistance: 100 milliohms maximum,
(15 milliohms initially).
Insulation Resistance: 10,000 Mohms
minimum between mutually insulated parts
(50,000 Mohms initially).
Voltage Breakdown: 600 Vac minimum
between mutually insulated parts at standard
atmospheric pressure.
Life Expectancy: As determined from the
load-life curve for the current to be switched.
Contact GRAYHILL for more information if any
of the following is true: the life limiting criteria are
more critical than those listed; longer operation
is required; a larger make and break current is
required; the operating environment includes
elevated temperatures or reduced pressures.
Contact Carry Rating: Switch will carry 6
amperes continuously with a maximum
contact temperature rise of 20°C.
Additional Characteristics
Contact Type and Forces: Shorting or non-
shorting wiping contacts with over 25 grams of
contact force.
Shaft Flat Orientation: Flat opposite contacting
position of pole number one (see circuit
diagrams).
Terminals: Switches have the full circle of
terminals, regardless of number of active
positions.
Stop Strength: 7.5 lb-in. minimum
Rotational Torque: 3.5 to 9 oz-in. (21-53
mN-m), depending on the number of poles.
Bushing Mounting: Required for switches with
stops, and recommended for switches without
stops.
Meets MIL-DTL-3786 for:
High and medium shock; Vibration (10 to 2,000
Hz); Thermal shock (-65° to 85 ° C); Salt spray;
Explosion; Stop strength (7.5 in-lbs. minimum (.85
N-m); Terminal strength; Sealed styles withstand
water pressure of 15 PSI minimum (103 KPa)
without leakage.

Panel is sealed by a at rub-
ber seal washer at the base of
bushing. Shaft is sealed by an
O-ring inside the bushing. After
the switch is mounted, seals do
not alter the dimensions of the
unsealed style.
Series 56 rotary switches are
available with a screwdriver
slotted shaft with dimensions as
shown. Available in the styles,
angles of throw and pole/posi-
tions combinations shown in
the choice and limitations chart.
Two stop pins and an adhesive backed sticker or
seal washer are provided. Sticker is temporarily
removed to locate stop pins as desired to limit
the shaft rotation. All dimensions are identical
to the xed stop switch counterpart.
In Inches (and millimeters)
Cut round hole for the bushing and for
the non-turn tab. Washer ts the double
D bushing ats. Washer is sold only when
accompanied by an order for a like number
of switches. Washer is 302 stainless steel.
