*Termination
A standard switch uses the entire 360° of each deck as required by the circuitry.
Thus one-sided termination is standard for Series 08, 36°, 1 pole switches with 1 to
5 positions per pole; it is also standard for Series 09, 30°, 1 pole switches with 1 to
6 positions per pole. Two-sided termination is standard for 1 pole switches with more
positions per pole and for switches of 2 or more poles per deck.
Special switches with one-sided termination can be made for circuitry which would
require two-sided termination in standard switches. Contact Grayhill for a special
part number. See also Special Options, page J-10.

SHAFT AND PANEL SEAL
A shaft and panel seal is available to provide watertight mounting of the Series 08
and 09. Standard and Military Style rotary switches. Sealing is accomplished by
O-ring shaft seal and panel seal washer. When the panel seal is compressed,
dimensions are approximately the same as an unsealed switch. Sealed switches are
provided with a double flat bushing. Non-turn feature can be accomplished by proper
fit of this bushing into panel hole and/or by allowing non-turn tab to extend into (but
not through) panel. Military Style rotary sealed switches do not have a non-turn tab.

Series 08 and 09 military switches are qualified
to MIL-DTL-3786/13. They include 30°, 36°, 45°
and 60° angles of throw with solder lug terminals
in sealed and unsealed styles. See front and
rear views at right. Standard variations which do
not affect switch performance can also be marked
as qualified product–contact Grayhill.
The military style is dimensionally the same as
the standard except for the solder lug. Convert
standard style switch drawings to military style
drawings by including this terminal detail and
changing the over-terminal dimensions shown
here. Grayhill can provide complete specification
drawings. Qualified switches can be ordered by
the Grayhill number or the "M" number; they will
be marked per MIL-DTL-3786/13.
SPECIFICATIONS
Electrical Ratings
Standard Style
Rated: To make and break the following loads:
1/4 amp, 115 Vac resistive; 1/4 amp, 6-28 Vdc
resistive; 20 mA, 115 Vdc resistive; 50 mA, 115
Vac inductive; 20 mA, 28 Vdc inductive; to carry
4 amps continuous.
Contact Resistance: After 25,000 cycles of
operation, 50 milliohms maximum
Insulation Resistance: 1,000 megohms
minimum between terminals and shaft
Voltage Breakdown: 1,000 Vac initially
(500 Vac or better after most environmental tests)
Life Expectancy: 50,000 mechanical cycles of
operation.
Note:
Actual life is determined by a
number of factors, including electrical loading,
rate of rotation and environment, as well as
maximum contact resistance, minimum insulation
resistance and minimum voltage breakdown
required at the end of life.
Electrical Ratings
Military Qualified
Qualified to the following MIL-DTL-3786/13
Circuit Values: (Also see Standard Style
description.) The Series 08M and 09M have been
tested to meet the requirements of MIL-S-3786,
Style SR13, the majority of which are listed. At
85°C, approximately 68% relative humidity and
sea level pressure, the switches have been tested
to make and break the following loads, as stated
in MIL-DTL-3786/SR13: 125 milliamperes at 28
Vdc resistive: 75 milliamperes at 115 Vac resistive.
The switches have also been tested at reduced
barometric pressure (70,000 feet), 25°C at
approximately 68% relative humidity to make and
break the following loads as stated in MIL-DTL-
3786/SR13. 50 milliamperes 28 Vdc resistive; 20
milliamperes 115 Vac resistive. When tested to
the above loads at the stated conditions, the
Series 08M and 09M switches meet the following
life-limiting criteria after 25,000 cycles of operation
in accordance with MIL-DTL-3786.
