How To Wire A Three-Prong Toggle Switch
The three pin toggle switch, also known as a three-terminal toggle switch, is a common electronic switch. Unlike a regular push button switch, it can change the circuit’s connection method by toggling the switch’s position. It consists of three pins: a control pin (usually called the base), an input pin (usually called the collector), and an output pin (usually called the emitter).
By toggling the switch, the connection between the input pin and the output pin can be switched from one state to another, in order to control the circuit. Common types of switches include ON-ON momentary switches and ON-OFF-ON toggle switches.
The ON ON momentary switch is a common type of three-pin toggle switch that can realize two different connection methods. When the switch is in one position, it connects the input pin to one output pin, and when it is in another position, it connects the input pin to another output pin.
This switch is often used to control two different circuits, such as selecting left or right channels in an audio amplifier.
The ON OFF ON toggle switch is also a common type of three pin toggle switch that can realize three different connection methods.
When the switch is in one position, it connects the input pin to one output pin, and when it is in another position, it connects the input pin to another output pin. When it is in the middle position, the input pin is not connected to any output pin. This switch is often used to control three different circuits, such as selecting left channel, right channel, or stereo in an audio amplifier.
Other types of three-pin toggle switches include ON OFF momentary toggle switches and SPDT (single pole, double throw) switches, in addition to ON-ON momentary toggle switches and ON-OFF-ON toggle switches.

Other types of three-pin toggle switches include ON OFF momentary toggle switches and SPDT (single pole, double throw) switches, in addition to ON-ON momentary toggle switches and ON-OFF-ON toggle switches.
SPDT switches have one control pin, one input pin, and two output pins. When the switch is in one position, the input pin is connected to one output pin, and when it is in another position, the input pin is connected to the other output pin. This type of switch is often used to control two different circuits, such as switching between left and right channels in an audio amplifier.
Three pin toggle switches are commonly used in electronic devices, such as amplifiers, power supplies, and logic circuits. They typically have a small square or circular plastic housing with a toggle switch and three pins. They operate similarly to mechanical switches, but control the current on the output pins by controlling the current on the control pin, thus controlling the circuit.
Three pin toggle switches have a wide range of applications, and here are some common ones:
- Signal amplification: Three pin toggle switches can function as amplifiers, amplifying input signals to the desired level, such as in audio amplifiers, RF amplifiers, and power amplifiers.
- Power control: Three pin toggle switches can serve as power toggle switch, controlling the on/off state of power supplies, such as in power management circuits, battery chargers, and voltage regulators in electronic devices.
- Logic control: Three pin toggle switches can be used in logic gate circuits, such as AND, OR, NOT gates, and multiplexers, etc.
- Signal modulation: Three pin toggle switches can be used as variable resistors or capacitors to adjust the amplitude or frequency of signals, such as in filters, modulators, and demodulators.
- Sensor interfaces: Three pin toggle switches can be used as signal processors in sensor interface circuits, amplifying and processing the output signals from sensors, such as in temperature sensors, photoelectric sensors, and pressure sensors.
These small toggle switches have the advantage of being compact and simple to install and use. They are usually constructed using plastic or metal materials and can be utilized in various applications, including regulating circuit switching states in household appliances or industrial equipment. Furthermore, these switches typically exhibit good reliability and durability, enabling them to endure numerous operations without succumbing to wear and tear or incurring damage.
