M1890-202-CPS - Cole Instrument Corp.

The ultimate in a one half-inch rotary selector switch, the Cole

series 1800 is engineered to meet or exceed applicable MIL-S-

3786, style SR20 requirements. A QPL version is also available.

The series 1800 is available with 1 pole, 2-10 positions and 2 pole, 2-5

positions. Available in standard solder lug or PC terminals, the Cole

Series 1800, with its unique design, renders the switch resistant to

water, contaminants, and most solvents.

The Series 1800 enclosed switch is designed for demanding usage

in aircraft, medical and industrial controls and instrumentation,

electronic equipment and critical ordnance applications.

Quality construction, using materials that meet the strictest standards,

allows these subminiature switches to combine high current switching

capacity with constant low contact resistance. Exceedingly stringent

inspection and testing procedures ensure long life and high reliability.

ORDERING INFORMATION

Begin by identifying the switch using the COLE

part numbering system as shown:

Indicate this is a SPECIAL switch to ensure that

no error is made when the order is entered.

Sample part number:

This sample part number orders a series 1800

standard style switch, 36° indexing, 2 poles, 5

positions per pole shorting, and push-to turn

isolation posts between positions 1-2, 2-3, and

3-4.

Although somewhat long, use of this numbering

scheme will prevent error in orders processing.

Upon receipt of your order, a special number

will be issued unique to this switch. These

numbers will not relate to the coding system

and will be logged as “special”.

The acknowledgment of your order will identify

this number. Your speciﬁ c switch will be the

only one identiﬁ ed by this number.

1800 SERIES

Half Inch Enclosed Rotary Switches

1800 Series/Page 7

1800 ISOLATED POSITION SWITCH DESCRIPTION

A special feature of rotary switches is available known as “isolated position”. This feature allows switch shaft rotation

that requires the user to either pull or push the shaft before it will respond to rotational torque. The user identiﬁ es the

position or positions affected by the isolation mechanism.

Incorporation of the isolated position feature in COLE’S SERIES 1800 switches will add 0.217 inches to the length.

SPECIFYING POSITIONS

The Cole System for identifying isolation positions lets you perform the selection by inserting isolation posts next to

the positions to be isolated. An 1800 series switch with 36° indexing and continuous rotation is shown below with no

isolation position identiﬁ ed in the spaces between the terminals.

10_1_2_3_4_5_6_7_8_9_10

If you isolate positions 1, 2 and 3, the isolation post insertion points are identiﬁ ed by the letters PL (for actuation by

pulling the shaft out), or PS ( for actuation by pushing the shaft in) as shown below:

10PL1PL2PL3PL4 5 6 7 8 9 10

This indicates that you can only get to positions 1, 2 and 3 by pulling on the shaft while all other positions can be

achieved with normal rotational torque on the shaft.

if A Push positions 1 and 2 are isolated from all other position but nor from each other:

10PS12PS3 4 5 6 7 8 9 10

In this case you need to push on the shaft to get to position 1 from position 10 as well as position 2 from position 3.

However, to get from position 1 to position 2 merely requires rotate the shaft from position 1 to 2 or 2 to 1.

As a special feature, certain positions on the switch can be isolated in unidirectional mode. That means that the

positions can be achieved with normal rotation on the shaft, but requires a push or pull action to get to the next

position (Ramp-In). Conversely, reaching the isolated position with a push or pull action on the shaft but requiring

normal rotation (Ramp-out) for the next position, is also available. Please contact the factory for special features.

SPECIFYING STOPS

Stops must be incorporated when a switch has multiple poles or speciﬁ es less than the numbers of positions

available. If a switch with 36° indexing is speciﬁ ed as an 8 position switch with position 1 isolated with push

actuation required, the designation would be:

STOP1PS2 3 4 5 6 7 8STOP

Since the stop mechanism is inserted between positions 10 and 1, the isolation post is only required between

positions 1 and 2. The stop mechanism inserted between terminals 8 and 9 serves to limit the switch to 8 positions.

When stop and isolation mechanism are used in multipole switches, all poles are slaved to the ﬁ rst pole in the case

of a 2 pole, 10 position switch with 36° indexing, isolating position 1 will automatically isolate position 6 too.

(Refer to the standard switch schematics for 36° indexing switches, page No. 4

DESCRIPTION:

A spring return rotary switch requires that manual torque

be maintained at the desired switch position. Releas-

ing the force allows the spring to return the contact to a

normal, or detent positions. Arrows in the CONFIGURA-

TIONS AND RESTRICTION TABLE indicate the direction

the spring will return the contact so it assumes a normal

detent position. The “D” designates a normal detent posi-

tion. (See Table Page 9).

1800 SPRING RETURN ROTARY SWITCH DESCRIPTION

A rotary switch with a spring return mechanism allows certain selected positions to have momentary action wherein

they can be maintained only with positive force on the shaft. Releasing the shaft will return the switch to its

previous position. This feature is available in the COLE SERIES 1800, 1830, and 3600 switches.

Addition of this mechanism to the SERIES 1800 switch adds 0.217 inches to its length; all other dimensions

remain unchanged.

The spring return feature in the SERIES 1800 switch is available in those with 36° and 45° angles of throw as

a standard.

Custom requirements can be accommodated by contacting the factory.
