The military style of the Series 71 rotary switch switchwithoutincreasingthenumberofoperative

is qualified to MIL-DTL-3786/39. Complete decks.

A shaft and panel seal is available to provide

watertight mounting of the Series 71 standard

military style rotary switches. Sealing is

accomplished by an O-ring shaft seal and a

panel seal washer. Panel seal dimension

differences are shown in the dimensional

drawings.Whenthepanelsealiscompressed,

dimensions are approximately the same as an

unsealed switch. If the non-turn washer

supplied with the switch is used, it should not

be allowed to extend entirely through the

panel when mounting a sealed switch.

However, the bushing may be used as a non-

turn device instead. Switches are provided

with a double flat bushing in styles which

include the letter A and with a bushing which

has a keyway in the styles which include the

letter B.

Electrical Ratings

Charts: Charts shown are for non-shorting

(breakbeforemake)contacts. Measurements

weremadeat25°Cand68%relativehumidity.

The load life curves show the number of

rotational cycles which can be expected for

the voltage, current and type of load. Thus,

for a standard style switch with a 300

milliampere 115 Vac resistive load, the

expected life is 15,000 cycles. Reducing the

load to 200 milliamperes increases the life to

25,000 cycles. Life limiting or failure criteria

are listed in the rating sections which follow.

Cycles: A cycle is a 360° rotation and a return

through all switch positions to the starting

position.

Curves are based on the following failure

criteria:

Contact Resistance: 50 milliohms maximum

(20 milliohms initially).

Insulation Resistance: 1,000 megohms

minimumbetweenterminalsandshaft. (50,000

megohms initially).

Voltage Breakdown: 500 Vac minimum

between mutually insulated parts.

Current Rating: 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, if

elevated temperatures or reduced pressures

are involved, Grayhill can predict the switch

life for the application.

Insulation Resistance: 1,000 megohms

minimum between terminals and shaft.

Dielectric Strength: 500 Vac (atmospheric

pressure) and 350 Vac (reduced pressure)

between mutually insulated parts.

The Series 71 also meets the requirements

Multi-Deck Rotary Switches

ADJUSTABLE STOPS

Set and Reset Stops to Limit Rotation

Form, Fit, Function Equivalent to Fixed Stop Styles

The adjustable stop Series 71 rotary switches allow you to

change the number of positions per pole. Simply remove

and relocate stop pins in the holes in the front of the switch.

The pins are held in place by a self adhesive sticker which

fits over the front plate.

This feature is available in the Series 71 single shaft

standard switches with either ¹/8" or ¹/4" diameter shafts

with either PC or solder lug terminals. It is not available in

military qualified or concentric shaft styles.

All dimensions, ratings and characteristics are the same as

the fixed stop equivalent. The chart shown here describes

the adjustable stop style substitutions for the fixed stop

styles. Although Series 71 is not an exact dimensional

equivalent of the fixed stop styles of Series 8 and 9, it most

nearly represents a functional substitution.

if the panel has been cut to fit the exact bushing shape. The bushing for

the /8" diameter shaft switch has a double flat; the /4" diameter shaft

switch has a keyway in the bushing. An alternate means of keeping the
