ORDERING INFORMATION
Indicate this as a SPECIAL switch to ensure
that no error is made when the order is entered.

CONVENTIONAL NUMBERS
Start ꢄy creating a conventional switch numꢄer
in the manner which follows:
Let's isolate position ( and position 2 from all
otherpositionsandfromeachother.Weindicate
isolation posts as shown here:
(2P(P2Pꢃ 4 ꢁ 6 5 7 9 (0 (( (2
To isolate just position (, descriꢄe like this:
(2P(P2 ꢃ 4 ꢁ 6 5 7 9 (0 (( (2
To isolate positions ( and 2 from all other
positions, ꢄut not from each other, do this:

DESCRIBING STOPS

This sample part numꢄer orders a Series 9
standard style, four deck, one pole per deck,
twelve positions per pole rotary switch with non-

Note: No stop arrangement suffix is needed.
See Descriꢄing Stops.
The word “STOP” indicates the conventional
switch stops, which limit rotation to positions (
through 6. To isolate position ( we insert only
one isolation post–ꢄetween terminals ( and 2.
The stop system already prevents rotation
ꢄeyond terminal (.
In multi-pole switches, the stop system and
isolation system descriꢄed for the first pole,
automatically affects the other poles. In the
example aꢄove, isolating position #( on the first
pole isolates the first position ꢀterminal #5ꢂ of
the second pole. See Standard Switch Pages
for a 2 pole circuit diagram for a ꢃ0° throw
switch.
DESCRIBING POSITIONS
Thislengthyordernumꢄerisrequiredtoprevent
any possiꢄle confusion in ordering the switch.
When we receive your order, we will assign a
special “short form” part numꢄer to facilitate
future identification of this special switch. This
numꢄer is sequentially assigned as the need
arises, and is non-descriptive. A typical “short

Contact Grayhill for price.
The Grayhill system for isolating positions lets
you choose the positions to ꢄe isolated. Grayhill
inserts isolation posts next to the positions to ꢄe
isolated. Consider a continuous rotation switch
of the Series 09A with a ꢃ0° angle of throw. The
terminals are listed here from ( through (2 with
