DESCRIPTION

A spring return rotary switch has 1 or more momentary positions. Maintaining contact at momentary
positions requires rotational force. Releasing the force allows the mechanism to return the contact
to a normal, or detent, position.

CONFIGURATIONS

This configuration indicates a counterclockwise
force is required to hold the switch at position
#1. “M” indicates a momentary position
counterclockwise of “D” and "D", detented ones.

Positions 1 2 3

Releasing this force breaks contact with position
#1 and returns the switch to #2. Normal rotary
switch detent action occurs when the switch is
rotated between position #2 and #3.

All of the configurations (except
basic 2 position arrangement which is shown in
italics. Example: MDDDDD or DDDDDM. Several
positions can be added during the switch
construction at the factory; but, any configuration
must always contain the 2 basic positions.

SELECTING A SWITCH

1. Select a Configuration: The total number of

positions always includes the 2 basic positions.
A (4) position switch of DDDDM configuration
would have 3 detent positions counterclockwise
of the momentary position.

2. Select Series, Angle of Throw, and Style:

See the Choices Chart. The basic switch
description, series, and throw are as follows:

1

/2", 1/4 Amp, multi-deck 08 = 36° 09 = 30°

1", 1 Amp, multi-deck 42 = 36° 44 = 30°

/2", 200 mA, single deck 50 = 36°
Electrical ratings are the same as those of the
conventional switches with the exception of life.
Life is limited to 10,000 cycles of operation
(25,000 cycles for Series 50) due to the spring
arrangement. Dimensions are the same as for

DESCRIPTION

An isolated position is one which cannot be reached by the normal rotation. An additional action is
required by the operator. It could be either Push-To-Turn, or Pull-To-Turn. After the switch is rotated
to the isolated position, releasing the shaft locks the switch in that position. Push or pull again to
rotate the switch again.

Use isolated positions to protect a switch position from indiscriminate rotation. Such safety positions
might include “calibrate”, “off” and/or “stand-by”.

CONVENTIONAL NUMBERS

Start by creating a conventional switch number
in the manner which follows:

Series & Style
Angle of Throw
Number of Decks

09A30-01-1-12N

Type of Contacts

Shorting = S
Non-Shorting = N

Positions Per Pole
Poles Per Deck

Note: No stop arrangement suffix is needed.
See Describing Stops.

DESCRIBING POSITIONS

The Grayhill system for isolating positions lets
you choose the positions to be isolated. Grayhill
inserts isolation posts next to the positions to be
isolated. Consider a continuous rotation switch
of the Series 09A with a 30° angle of throw. The
terminals are listed here from 1 through 12 with
a space between each to indicate where isolation
posts might be inserted.

12123456789101112

Let's isolate position 1 and position 2 from all
other positions and from each other. We indicate
isolation posts as shown here:

12P1P2P3 4 5 6 7 8 9 10 11 12

To isolate just position 1, describe like this:

12P1P2 3 4 5 6 7 8 9 10 11 12
To isolate positions 1 and 2 from all other
positions, but not from each other, do this:

12P1 2P3 4 5 6 7 8 9 10 11 12

DESCRIBING STOPS

When a 1-pole switch has less than the maximum
number of positions, consider also the stop
system. Following is the arrangement for a 6
position switch with the position 1 isolated.

STOP 1P2 3 4 5 6 STOP
The word “STOP” indicates the conventional
switch stops, which limit rotation to positions 1
through 6. To isolate position 1 we insert only
one isolation post–between terminals 1 and 2.
The stop system already prevents rotation
beyond terminal 1.
In multi-pole switches, the stop system and
isolation system described for the first pole,
automatically affects the other poles. In the
example above, isolating position #1 on the first
pole isolates the first position (terminal #7) of
the second pole. See Standard Switch Pages
for a 2 pole circuit diagram for a 30° throw
switch.

ORDERING INFORMATION

Indicate this as a SPECIAL switch to ensure
that no error is made when the order is entered.
Sample part number:

SPECIAL

09A30-04-1-12N

PULL 12P1P2P3 4 5 6 7 8 9 10 11 12

This sample part number orders a Series 9
standard style, four deck, one pole per deck,
twelve positions per pole rotary switch with non­shorting contacts and isolation posts between
positions 12 and 1, between 1 and 2, and
between 2 and 3.

This lengthy order number is required to prevent
any possible confusion in ordering the switch.
When we receive your order, we will assign a
special “short form” part number to facilitate
future identification of this special switch. This
number is sequentially assigned as the need
arises, and is non-descriptive. A typical “short
form” special part number might be 09YY12345.
