How to Use Transistor as a Switch

Transistor as a swith motor control example off condition

A transistor is an electronic component that is also used as a digital switch. It works similarly to a mechanical switch, but it is controlled by a digital high logic signal instead of traditional push buttons. Traditional switches are manually controlled by applying mechanical force. Recommended Books Books that cover this topic in more depth. … Read more
