Special Function Rotary Switches SERIES 09, 42, 44, 50, 51 Isolated Position FEATURES • Protected Switch Positions For Safety, Calibration, or Stand-by • Choice of Push- or Pull-To-Turn • 1/2" Diameter, 200 mA and 1" Diameter, 1 Amp Switch • 10,000 Cycles of Operation 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”.

All other dimensions remain unchanged. In Series 9, 42 and 44, it has the appearance of an additional deck section without terminals, located directly behind the detent system. Electrical Ratings Materials and Finishes The switching elements, and therefore ratings, are the same in an isolated position switch as in a conventional rotary switch. Mechanical life is also the same. Materials and finishes for the isolation mechanism are listed here.

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. 12 1 2 3 4 5 6 7 8 9 10 11 12 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 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 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. Grayhill, Inc. • 561 Hillgrove Avenue • LaGrange, Illinois 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. Contact Grayhill for price.
