1. INTRODUCTION
This instruction sheet covers the use of the Low Profile
Rotary Switches shown in Figure 1. Read these instruc-
tions carefully before installing any switches.
All dimensions on this document are in metric
units [with U.S. customary units in brackets].
Figures and illustrations are for identification only
and are not drawn to scale.
See Section 6, REVISION SUMMARY, for revision
information.
2. DESCRIPTION
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
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.
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.
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.

3. INSTALLATION
Determine the number of selector positions, printed cir-
cuit pads, and the circuit pattern required for the
application. Then refer to the table in Figure 1 and select
the applicable switch.
The solder posts of the switch are polarized to
ensure proper installation. Make certain they
align with the holes before attempting to insert
the switch in the pc board, otherwise damage
may result.
Proceed as follows:
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.
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.

4. 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.
4. SOLDERING
4.1. Wave Soldering
The switch does not have to be in any specific
position before soldering.
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.
Do NOT allow the switch to be exposed to the
solder wave for more than five seconds or
damage to the switch could occur.
4.2. Hand Soldering
The switch does not have to be in any specific
position before soldering.
1. Make sure the switch is fully bottomed on the pc
board.
2. Using a soldering iron (47 watts maximum),
simultaneously apply heat and solder to the pc
board and switch lead for approximately five
seconds.
5. CLEANING
(Figure 4)
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]. Recom-
mended cleaning solutions are listed in the chart in
Figure 4.
Vapor cleaning (with pc board on edge) is
preferred over immersion in a liquid solvent.
