STANDARD STYLEMILITARY QUALIFIED

The Series 53, 57 and 59 rotary switches are allmilitary type switches. Grayhill manufacturesthese switches in two styles: M and HS. Style Mis unsealed and is not qualified; Style HS is shaftand panel sealed and is qualified. The non-qualified Style M can be regarded as ourStandard Style for types of switches. Althoughit is not qualified, Style M is constructed of thesame military grade materials and will providecomparable performance in all areas. Forexample, the Style ‘M’ switches, in addition tothe electrical ratings listed elsewhere in thesepages, will meet the following requirements ofMIL-DTL-3786:

Moisture Resistance: Medium and High Shock;Vibration (10 to 500 cps); Thermal Shock (-65°C to 125 °C); Salt Spray; Explosion; TerminalStrength (pull, 2 lbs. minimum); and StopStrength (15 pound-inches minimum).

The line drawings shown above are applicableto the Style M and Style HS. The only differencebetween the two is the length of the tab of thenon-turn washer. The shorter tab for the HS isexplained in the following paragraph.

The Series 53, 57 and 59 Style HS rotaryswitches are qualified to MIL-DTL-3786/36. TheStyle HS is shaft and panel sealed. The panel issealed by an O-ring at the base of the bushing.The shaft is sealed by an O-ring inside thebushing. These seals do not alter the dimensionsshown in the line drawings when the switch ismounted.

A non-turn washer, supplied with the mountinghardware, may be used with the Style HSswitches. It is suggested that the non-turn washerbe mounted in the following manner to preservethe seal: from the front of the panel into a holethat does not go through the panel.

The qualification of the Series 53, 57 and 59rotary switches does not extend to all possiblecombinations listed in the Choices andLimitations chart. The limitations on thequalification are described in the chart shownbelow.
