Lesson 10 Slide Switch
Introduction
In this lesson, we will learn how to use a Slide Switch. Usually, the slide switch is soldered on
PCB as a power switch, but here we need to insert it into the breadboard, thus it may not be
tightened. And we use it on the breadboard is to show its function.

Principle
Slide Sw itch
A slide switch, just as its name implies, is to slide the sw itch bar to connect or break the circuit,
and further switch circuits. The common-used types are SPDT, SPTT, DPDT, DPTT etc. The Slide
Switch is commonly used in low-v oltage circuit. It features flexibility and stability, and widely
applies in electric instruments and electric toys.
How it works: Use the middle pin as the fixed one. When you pull the slide to the left, the left
two pins are connected; to the right, the right two pins connected. Thus, it connects and
disconnects circuits as a sw itch. See the figure below:
The circuit symbol of the slide switch is as shown below . 2 in the figure means the middle pin.
