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.
