11. Intermixing of Shorting and
In some switches, non-shorting and shorting
contacts can be intermixed between decks. A
2-deck switch, for example could have shorting
contacts on deck 1 and non-shorting contacts
on deck 2. In a few switches, non-shorting and
shorting contacts can also be intermixed
between poles. A 2-pole per deck switch, for
example, could have non-shorting on pole #1,
and shorting on pole #2.
Series 08 and 09:
An 09M30 or 08M36 rotary switch can have
shorting and non-shorting contacts intermixed
between decks. Shorting and non-shorting
contacts can be intermixed between poles as
well as decks in styles A, S, P, and SP.
Series 42, 43, 44, and 54, in 30° or 36°:
Non-shorting and shorting contacts can be
intermixed between poles or decks.
Series 50, 51, and 56:
Non-shorting and shorting contacts can be
intermixed between poles.
Series 71:
Non-shorting and shorting contacts can be
intermixed between poles in fixed stop switches
only.
Priced the same as standard switches. The
type of contacts on each pole must be precisely
indicated.
12. PC Mount Switches With
Series 71 PC mount switch has all terminals on
one side.
Series 08P, 09P, and 42P with non-shorting
contacts are also available with terminals limited
to one side. Contact Grayhill for a special part
number. This is accomplished by using 2 decks
per pole and placing the rotating contacts 180°
out of phase on each deck. The first deck picks
up the first half of the positions; the second deck
picks up the last half of the positions. Common
terminals are tied together by the PC board
circuitry.
A total of 12 decks (6 usable poles) is the
maximum per switch. Switches with the
maximum number of positions (12 for 30°, or 10
for 36°) will have continuous rotation. Rotation
can be limited to less than the maximum
positions. For example, an 8 position Series
8P36 switch with terminals on one side, would
pick up 5 positions on the first deck and 3
positions on the second deck.
Price is the same as standard switches with
comparable number of decks and positions.
Example: an 08P36, 1-pole, 10 position switch

with terminals on one side of the switch would be
priced as a 2 deck, five position, one pole per
deck switch.
13. Homing Rotor (Bridging and
A homing rotor (bridging and shorting) switch
deck connects all terminals to the common
except the terminal in the selected switch position.
For example, in position 1, terminals 2 thru 12
are connected to the common, and terminal 1 is
open. In position 2, terminal 3 thru 12 and 1 are
connected to the common, and terminal 2 is
open. A homing rotor deck will function for
25,000 mechanical cycles of operation.
The progressively shorting switch deck connects
consecutive switch positions to the common.
For example, in position 1, terminal 1 is connected
to the common; in position 2, terminals 1 and 2
are connected to the common; in position 3,
terminals 1,2, and 3 are connected to the
common. A progressively shorting deck is limited
to a maximum of 6 positions. A progressively
shorting deck will function for 25,000 mechanical
cycles of operation.
Homing Rotor or Progressively Shorting decks
can be ordered as a deck of a 44A or 44M style
switch, or their sealed equivalents. Order up to
11 conventional decks and 1 special circuitry
deck. For a good detent feel, the switch is limited
to a total of 12 poles plus the homing rotor or
progressively shorting deck. Example: 6 2-pole
decks and a homing rotor. When these special
decks are used in combination with conventional

decks, it is important to remember that the stop
system limits the rotation of both types of decks.
For example, when a homing rotor deck Is used
in combination with a 6-position conventional
deck, the homing rotor is likewise limited to six
positions.
14. Shaft and Panel Seal on
The following diagram shows the location of the
O-rings required to seal the shafts to the
bushings. When the concentric shaft switches
are sealed in this manner, the .125 inch diameter
shaft is supplied full round. Bushing-to-panel
sealing is accomplished by the panel seal kit.
15. Fixed Stop, Add-A-Pot
The rotary switch section of the Add-A-Pot
rotary switches can be built with a fixed
mechanism rather than the standard adjustable
stop mechanism. The front end of a switch of
this type is similar to the Series 43A or Series
54A style concentric rotary switches. The total
number of decks is limited to three. The Series
43 is limited to 1 pole per deck. Series 54 to 2
poles per deck.
16. Series 54 Concentric Shaft
The Series 54A switch is available with these
angles of throw in Section A of the concentric
rotary switch. Section B is available in 30° angle
of throw only. Section A is limited to 1 to 3 decks,
non-shorting contacts, and 1 or 2 poles per
deck.
