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

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
