Single Deck Rotary Switches
Military Qualification
The dimensions for qualified switches are the same as those indicated in the drawings of standard switches. Switches with standard variations, such as shaft and bushing length, which do not affect switch performance, can be marked as qualified product. Contact Grayhill for complete information on variations.
36°, 45°, 60°, 90° (Series 50): The C and M style switches are qualified to MIL-S-3786/20. They include the following: Solder lug or PC terminals With or without panel seal Series 50 qualified switches may be ordered by the ‘M’ number or by the Grayhill part number. 30° (Series 51): The C and M style switches are qualified to MIL-S-3786/35. They include the following: Solder lug or PC terminals With or without panel seal Series 51 qualified switches may be ordered by the ‘M’ number or by the Grayhill part number.
SPECIFICATIONS: Other
Electrical Ratings
Life Expectancy: With the limiting criteria stated
here, the Series 50 and 51 with non-shorting contacts will switch the following loads at atmospheric and reduced pressures for 25,000 cycles of operations. One cycle is 360° rotation clockwise and 360° return.
At 85°C, atmospheric pressure 200 mA, 28 Vdc resistive 150 mA, 115 Vac resistive 30 mA, 28 Vdc inductive 100 mA, 28 Vdc lamp load 75 mA, 220 Vac lamp load
At 25°C, reduced pressure (70,000 feet) 200 mA, 28 Vdc resistive 150 mA, 115 Vac resistive 75 mA, 220 Vac resistive Contact Resistance: 20 milliohms maximum, (10 milliohms initially).
Insulation Resistance: 1,000 Mohms minimum between mutually insulated parts. Voltage Breakdown: 600 Vac minimum between mutually insulated parts at standard atmospheric pressure. Life Expectancy: Listed for the voltage source and make and break current levels. Contact Grayhill for more information if any of the following is true: the life limiting criteria are more critical than those listed; longer operation is required; a larger make and break current is required; the operating environment includes elevated temperatures or reduced pressures. Contact Carry Rating: Switch will carry 6 amperes continuously with a maximum contact temperature rise of 20°C.
Rotary Switches
Additional Characteristics
Contact Type and Forces: Shorting or non-
shorting wiping contacts with over 80 grams of contact force. Shaft Flat Orientation: Flat op posite contacting position of pole number one (see circuit diagrams). Terminals: Switches have the full circle of terminals, regardless of number of active position.
Stop Strength: 7.5 pound-inches minimum Rotational Torque: 8–24 ounce-inches,
depending on the number of poles.
PROCESS SEALED–Style T
Switch can be mounted on PC board with other components and subjected to wave soldering and conventional board cleaning techniques. No secondary wiring or soldering is necessary.
Bushing is o-ring sealed; epoxy potting seals the terminals and the rear of the switch. Designed for PC assembly, this sealing technique can also be applied to solder lug terminal switches. A bushing to panel seal can also be added to the process sealed versions. Military qualified ver­sions are available, see ordering information.
Materials and Finishes
Switch Base: Thermoset Detent Rotor: Nylon Shaft, Stop Blades, Stop Arm, Thrust washer, and Retaining Ring: Stainless steel Detent Balls: Steel, nickel-plated Bushing:Zinc,tin-zincplated Detent and Contact Springs: Stainless steel Common Ring: Brass, gold-plated over silver
plate. Terminals: Brass, gold-plated over silver plate and nickel plate
1/4" SHAFT: Style K
Rotor Contact: Precious metal alloy, gold-
plated
Panel Seal: Silicone rubber Shaft Seal: Fluorosilicone Mounting Nuts:Brass,tin-zincplated Mounting Hardware: One mounting nut .089"
thick by .375" across flats and one internal tooth lockwasher are supplied with the switch. Maximum Mounting Torque: 15in-lbs

*Form fit and function equivalents, but not watertight sealed to the panel.
ADJUSTABLE STOPS: Style D
Adjustable stops permit the user to set and reset the number of positions per poles. Shown in the diagram, a plastic washer can be removed to reveal slots at the base of the bushing. Stop blades can be inserted into the appropriate slots to limit switch rotation. Positions per pole configuration can thus be changed to meet the needs of the application. Dimensions are the same as the fixed stop version, when plastic washer is in place. Most desirable for prototype work. Readily available from local distributor.
SHAFT AND PANEL SEAL: Styles S and M
SCREWDRIVER SLOTTED SHAFT: Style B
METRIC SHAFT AND BUSHING: Style E
Shaft and panel seal switches are watertight to the panel. They are not totally process sealed like the Style “T”. Panel is sealed by a gasket at the base of the bushing. Shaft is sealed by an O-ring inside the bushing. After mounting, seals do not alter switch dimensions. See Style “S” (standard switches) and Style “M” (military switches) in the Choices and Limitations chart.
Form, fit and function equivalent to standard shaft switches. The dimensions shown have evolved as the most popular for this type of switch. See Style “B” in the Choices and Limitations chart . Previous users may have ordered these switches by a non-descriptive part num­ber containing a “Y”. Contact Grayhill, if in doubt about a cross-reference.
Metric standard dimensions for the shaft and bushing are shown in the drawing. Other dimensions approximately the same as shown in dimensional drawing. Contact Grayhill for exact dimensions. See Style “E” in the Choices and Limitations chart.
ACCESSORY: Non-Turn Washers
