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.
