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.
