The “SA-5000 Series” are divided into 3 types

according to the kind of a built-in circuit.

ꢀꢁA type: Built-in resistors (Housing color Yellow)

ꢀꢁC and D type: Built-in diodes (Housing color Black)

In order to use conventional code switches in a digital circuit, pull-

up or pull-down resistors must be connected externally. This type

contains these resistors.

When using more than one code switch arranged as a code of

plural figures, the digital circuit makes a comparison of signals

received through a line called a common bus line as its own

method. For this, it is necessary to connect a diode for preventing

reverse current to the middle of output terminal of each switch and

a bus line. The product is a hybrid switch integrating such a diode.

Diodes of C and D types are set in a reverse direction.

ꢀꢁB type: Pulling-up resistors and built-in diodes

(Housing color Red)
