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. The “SA-5000 Series” are divided into 3 types according to the kind of a built-in circuit. O A type: Built-in resistors (Housing color Yellow) 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. O B type: Pulling-up resistors and built-in diodes (Housing color Red) SA-5000 ROTARY CODED SWITCHES ① ② ③ ④ ⑤ ⑥ ⑦ ⑧ ⑨ ⑩ RoHS compliant |
