Single Deck Rotary Switches
SPECIFICATIONS
Military Qualification
Electrical Ratings
The dimensions for qualified switches are the
same as those indicated in the drawings of
standard switches. Switches with standard
variations, such as shaft and bushing length,
which do not affect switch performance, can
be marked as qualified product. Contact
Life Expectancy: With the limiting criteria stated
here, the Series 50 and 51 with non-shorting
contacts will switch the following loads at
atmospheric and reduced pressures for 25,000
cycles of operations. One cycle is 360 ° rotation
clockwise and 360 ° return.
Contact Resistance: 20 milliohms maximum,
(10 milliohms initially).
Insulation Resistance: 1,000 Mohms
minimum between mutually insulated parts.
Voltage Breakdown: 600 Vac minimum
between mutually insulated parts at standard
Grayhill for complete information on variations.
At 85 ° C, atmospheric pressure
atmospheric pressure.
Life Expectancy: Listed for the voltage source
36 ° , 45 ° , 60 ° , 90 ° (Series 50): The C and M
style switches are qualified to MIL-S-3786/20.
They include the following:
Solder lug or PC terminals
With or without panel seal
Series 50 qualified switches may be ordered
by the ‘ M ’ number or by the Grayhill part
number.
30 ° (Series 51): The C and M style switches
are qualified to MIL-S-3786/35. They include
the following:
Solder lug or PC terminals
With or without panel seal
Series 51 qualified switches may be ordered
by the ‘ M ’ number or by the Grayhill part
number.
SPECIFICATIONS: Other
Additional Characteristics
Contact Type and Forces: Shorting or non-
shorting wiping contacts with over 80 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
position.
Stop Strength: 7.5 pound-inches minimum
Rotational Torque: 8 – 24 ounce-inches,
depending on the number of poles.
PROCESS SEALED – Style T
Switch can be mounted on PC board with other
components and subjected to wave soldering
and conventional board cleaning techniques.
No secondary wiring or soldering is necessary.
Bushing is o-ring sealed; epoxy potting seals
the terminals and the rear of the switch. De-
signed for PC assembly, this sealing technique

and make and break current levels. 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.
Panel Seal: Silicone rubber
Shaft Seal: Fluorosilicone
Mounting Nuts: Brass, zinc-plated
Mounting Hardware: One mounting nut .089"
thick by .375" across flats and one internal
tooth lockwasher are supplied with the switch.
