Input / output yam ntxwv:

Nyob rau ntawm qhov chaw input tam sim no

> 2.1mA, cov zis raug kaw, qhia ON;
Thaum

Switched tswj ntawm inverted theem thiab ib txwm theem ntawm outputs ec

Thaum lub dial hloov K1 nyob rau ntawm "ON", lub transistor tso zis ec nyob rau hauv inverted theem
Thaum lub dial hloov K1 nyob rau ntawm "OFF", lub transistor tso zis ec nyob rau hauv ib txwm theem
Thaum K2 nyob ntawm "ON", lub voj voog yuav xaiv lub teeb liab LFD qhia lub tswb muaj nuj nqi

Cov zis tawm hauv thaj chaw nyab xeeb

Tso zis teeb liab

Relay thiab tswb relay (yeem)

Output yam ntxwv

NPN hom transistor emitter lossis collector qhib Circuit Court tso zis
