# Slide Switch

## Introduction of Slide Switch

• Slide switches are mechanical switches defined by their method of Operation.

• In this switch there is a slider that moves(slides) from position to position linearly making it easy to ON/OFF circuit or as selector switch with a finger tip easily.

• Slide switch has a rectangle casing with a bar handle which slides from one position to another changing its state.

• It can handle between a 1/10th of an amp to several amps of current, and up to about 200 volts, which depends on the size of the switch.

• It has 0.1" spacing making it easy to mount on the pcb and making it advantageous over toggle switch.

• ## Types of Slide Switch based on switching terminology

• SPDT slide switches make or break the connection of a single conductor with either of two other single conductors. These switches usually have three terminals and are commonly used in pairs.

• SPST slide switches make or break the connection of a single conductor in a single branch circuit. This switch type typically has two terminals and is referred to as a single-pole switch.

• SPDT slide switches make or break the connection of a single conductor with either of two other single conductors. These switches usually have three terminals and are commonly used in pairs.

• SPDT switches are sometimes called three-way switches.

• DPST slide switches make or break the connection of two circuit conductors in a single branch circuit. They usually have four terminals.

• DPDT slide switches make or break the connection of two conductors to two separate circuits. They usually have six terminals are available in both momentary and maintained contact versions.
