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 identies 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 identied 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 identied 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 species less than the numbers of positions
available. If a switch with 36° indexing is specied 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 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
