3 Terminal Toggle Switch

SPST switches are the simplest type of 3-pin toggle switch. They have two terminals and are used to connect or disconnect a single circuit. SPDT switches have three terminals and can be used to connect or disconnect two circuits at the same time. DPST switches have four terminals and are used to control two separate circuits with a single switch. DPDT switches have six terminals and are used to control two separate circuits with two separate switches.

3-pin toggle switches are used in many different applications. They are commonly used in electronic devices, appliances, and even in automotive applications. They are used to turn on and off lights, fans, motors, and other electrical components. They are also used in audio systems to switch between different audio sources.

In conclusion, a 3-pin toggle switch is a simple yet versatile electrical switch that can be used in many different applications. It is easy to install and use, and its rating should be carefully considered when choosing the right switch for a particular application. With its various types and functions, it is an essential component in many electrical systems.

A SPST toggle switch (Single-Pole Single-Throw) is a fundamental electrical component designed for simple on/off circuit control. The term "single-pole" refers to a single electrical circuit or pole that the switch controls, while "single-throw" means it has only two possible states: on (closed circuit, allowing current flow) or off (open circuit, interrupting current). This straightforward design makes it one of the most common toggle switch types for basic applications.

Key Features

1. Simple Operation:

• A toggle lever physically connects or disconnects the circuit when moved.

• No intermediate positions; it remains in the chosen state until manually switched.

2. Compact Design:

• Available in mini or subminiature sizes, ideal for space-constrained devices.

3. Durable Construction:

• Built with materials like plastic or metal housings and corrosion-resistant contacts (e.g., silver or copper alloys) for reliable performance.

4. Voltage/Current Ratings:

• Typically handles low to moderate power (e.g., 12V DC, 500mA to 5A), depending on the model.
