Special Function Rotary Switches SERIES 08,09,42,44,50 Spring Return FEATURES • Hold-To-Test, Hold-To-Calibrate, And Other Momentary Applications • Choice of Configurations, Ratings, Styles and Circuitry • 10,000 Cycles of Operation 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 SELECTING A SWITCH OPTIONS 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 M D D 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. 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. Watertight panel seal; Multi-pole switches that exceed the limits noted in the Selector Chart; Series 50 MD or DM configurations in Military styles; Series 08, 09, & 44 in MMMDM MM, and in MMDD MM, and in MMMMMD. Not available through Distributors All of the configurations (except MDM) list a 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.

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° 1 /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 conventional types except for the shaft flat orientation of the 3, 4, 5, and 6 pole, Series 09 and 44 in the DDDDDM configuration (see chart). 3. Select Poles & Positions Per Pole: If you do not find the poles and positions per pole you need in one series, try another or contact the factory. If the behind panel length is a problem, select a multi-pole type instead of a single deck.
