Slide Switch

img_slide

A slide switch, as the name suggests, operates by sliding a switch bar to open or close a circuit, allowing it to toggle between different circuits. Common types include SPDT, SPTT, DPDT, and DPTT. Slide switches are often used in low-voltage circuits due to their flexibility, stability, and wide application in electronic instruments and toys.

How It Works

The middle pin serves as the fixed connection point. When the slide bar is moved to the left, the two pins on the left become connected. Similarly, moving the slide bar to the right connects the two pins on the right. This mechanism enables the switch to establish or break connections between circuits. Refer to the diagram below for a visual representation.
