INTRODUCTION This instruction sheet covers the use of the Low Profile Rotary Switches shown in Figure 1. Read these instructions carefully before installing any switches. NOTE All dimensions on this document are in metric three different styles: slot switch, knob switch, and thumbwheel switch. The circuit pattern for each code is shown in Figure 2. Make certain the circuit pattern of the switch used matches the circuit layout of the applicable pc board. 2. DESCRIPTION The slotted switch is designed for minimal clearance locations. A screwdriver or similar tool can be used to rotate the selector. The knob switch can be used at similar locations with the exception that more space is required between the applicable pc board and adjacent components. These switches must be installed in locations that provide accessibility to the front of the switch or in pc boards that can be removed for programming of the switch. These switches are bi-directional programming devices that are designed to be soldered to printed circuit (pc) boards. They are available with five coded readouts: (1) Binary Coded Decimal (BCD); (2) Binary Coded Octal (BCO); (3) Decimal; (4) Hexadecimal; and (5) 16-Position Single Pole. The switches feature The thumbwheel switch is recommended for pc boards that are placed in a fixed position adjacent to existing components. This switch is designed to be rotated from the edge of the pc board. When installing this switch, make certain the selector will face a readable position. units [with U.S. customary units in brackets]. i Figures and illustrations are for identification only and are not drawn to scale.

Then refer to the table in Figure 1 and select the applicable switch. CAUTION The solder posts of the switch are polarized to 1. Align the selector and ``0'' character as shown in Figure 1. This provides a datum that will aid in alignment of the solder posts. 2. Align the solder posts with the holes in the pc board. Then start them into the board. ensure proper installation. Make certain they ! align with the holes before attempting to insert the switch in the pc board, otherwise damage may result. 2 of 3 3. Press on the outer edge of the switch until it bottoms on the pc board. Do not press on the center of the switch. See Figure 3.

Make certain the switch is flat against the pc board. Then solder the posts to the circuit pads using a standard wave soldering or hand soldering technique. Vapor cleaning (with pc board on edge) is NOTE 4. SOLDERING preferred over immersion in a liquid solvent. i 4.1. Wave Soldering NOTE Clean the pc board with a cleaning solution that is free of contamination and dissolved flux (3% maximum), and one that will NOT affect plastic, nor subject the switches to solvent temperatures above 52_C [125_F]. Recommended cleaning solutions are listed in the chart in Figure 4. The switch does not have to be in any specific CLEANING SOLVENTS position before soldering. i 1. Preheat pc board and keep the temperature regulated so that the switch case does not exceed 88_C [190_F]. 2. Apply flux only to the bottom of the pc board. Do NOT allow flux to pass over the top of the pc board. 3. Keeping the solder temperature at 260_C [500_F] pass the pc board over the solder wave. CAUTION Do NOT allow the switch to be exposed to the solder wave for more than five seconds or ! Rev A damage to the switch could occur.
