STANDARD STYLE
MILITARY QUALIFIED
The Series 53, 57 and 59 rotary switches are all
military type switches. Grayhill manufactures
these switches in two styles: M and HS. Style M
is unsealed and is
not
qualified; Style HS is shaft
and panel sealed and
is
qualified. The non-
qualified Style M can be regarded as our
Standard Style for types of switches. Although
it is not qualified, Style M is constructed of the
same military grade materials and will provide
comparable performance in all areas. For
example, the Style ‘M’ switches, in addition to
the electrical ratings listed elsewhere in these
pages, will meet the following requirements of
MIL-DTL-3786:
Moisture Resistance: Medium and High Shock;
Vibration (10 to 500 cps); Thermal Shock (-65
°C to 125 °C); Salt Spray; Explosion; Terminal
Strength (pull, 2 lbs. minimum); and Stop
Strength (15 pound-inches minimum).
The line drawings shown above are applicable
to the Style M and Style HS. The only difference
between the two is the length of the tab of the
non-turn washer. The shorter tab for the HS is
explained in the following paragraph.
The Series 53, 57 and 59 Style HS rotary
switches are qualified to MIL-DTL-3786/36. The
Style HS is shaft and panel sealed. The panel is
sealed by an O-ring at the base of the bushing.
The shaft is sealed by an O-ring inside the
bushing. These seals do not alter the dimensions
shown in the line drawings when the switch is
mounted.
A non-turn washer, supplied with the mounting
hardware, may be used with the Style HS
switches. It is suggested that the non-turn washer
be mounted in the following manner to preserve
the seal: from the front of the panel into a hole
that does not go through the panel.
The qualification of the Series 53, 57 and 59
rotary switches does not extend to all possible
combinations listed in the Choices and
Limitations chart. The limitations on the
qualification are described in the chart shown
below.
Standard variations, such as shaft and/or
bushing length, etc., that do not affect switch
performance can also be marked as qualified
product. For complete details contact Grayhill.
Military qualified Series 53, 57 and 59 Style HS
rotary switches may be ordered by the ‘M’
number listed in MIL-DTL-3786/36 or by the
Grayhill part number. Military style switches
will be marked to the specification.
Style HS Switches are MIL-DTL-3786/36

milliamperes, 30 Vdc resistive load, 10,000
cycles of life can be expected. Life limiting or
failure criteria for these curves are:
Contact Resistance:
50 milliohms maximum
(20 milliohms initially).
Insulation Resistance:
1,000 megohms

Voltage Breakdown:
500 Vac minimum
between mutually insulated parts. These
switches will carry 4 amperes with a maximum
contact temperature rise of 20°C. If the life
limiting characteristics are less critical than
those shown above or if elevated temperatures
or reduced pressures are involved, Grayhill can

The Series 53, 57 and 59 Style HS, Rotary
Switches have been tested to make and break
the following loads as stated in MIL-DTL-3786/
36: 70,000 ft. altitude for 10,000 cycles: 10mA,
28 Vdc, inductive (250 mH); 50 mA, 28 Vdc,
resistive; 20 mA, 115 Vac, resistive. Atmospheric
pressure, 125°C for 10,000 cycles: 25 mA,
28 Vdc inductive (250 mH); 75 mA, 28 Vdc,
resistive; 50 mA, 115 Vac resistive. Atmospheric

28 Vdc, inductive (250 mH); 250 mA, 28 Vdc
resistive; 150 mA, 115 Vac, resistive. Life limiting
criteria for these loads are:
Contact Resistance:
50 milliohms maximum.
Dielectric Strength:
500 Vac (350 Vac—
reduced pressure).
Insulation Resistance:
1,000 megohms
minimum. These switches also meet MIL-DTL-

Additional Characteristics
Rotational Torque:
20-80 in-ozs., depending
on the number of poles per deck and the
number of decks.
Contacts:
Shorting or non-shorting wiping
contacts with over 100 grams of contact force.
Shaft Flat Orientation:
Flat opposite
contacting position pole #1 (See Circuit
Diagrams).
Extended Studs:
Switches of 6 decks or
more have longer studs with extra stud nuts
for recommended double end mounting.
Terminals:
Switch is provided with full
complement of base or position terminals
regardless of the number of active positions.
Curve data based on test data conducted at
sea level, 25°C and relative humidity. Cycle
equals 360° rotation and 360° return. Cycling
rate is 10 cycles per minute. The curves
shown are typical load life curves for a Series
53M, 57M and 59M Rotary Switch. They show
the number of cycles of rotational life that can
be expected for the voltages, currents and
