DPDT (Double Pole Double Throw) Switch

Product Description

The DPDT (Double Pole Double Throw) Switch is a 6-pin spring-loaded rocker switch designed for controlling the direction of DC motors. By wiring the switch in a cross-polarity configuration, it can reverse the motor’s polarity, allowing the motor to rotate in forward or reverse directions.

It is commonly used in wired robot controllers, school robotics projects, RC vehicles, motor control systems, and DIY automation projects.

Forward & Reverse Motor Control

The DPDT switch uses six terminals arranged into two poles with three positions. In an ON-OFF-ON configuration, the center position disconnects the motor, while the two outer positions provide opposite polarity to the motor.

This makes it a simple manual solution for controlling one DC motor in both directions without requiring a microcontroller or motor-driver circuit.

Spring-Loaded Operation

The switch is designed with a spring-loaded action, providing a clear switching response and convenient manual motor control. Its panel-mount design allows it to be installed into suitable robot controllers, enclosures, and control panels.

Technical Specifications

Working Principle

The DPDT switch changes the polarity supplied to the motor. With suitable cross-wiring, one switch position applies positive and negative voltage in one direction, while the opposite position reverses the polarity.

The center position disconnects the motor, providing an OFF state.

Motor Reversing Wiring

For the cross-wired configuration:

• Connect Battery Positive (+) to Pin 3.
• Connect Battery Negative (-) to Pin 4.
• Connect Pin 1 to Pin 6.
• Connect Pin 2 to Pin 5.
• Connect the motor wires to Pin 1 and Pin 2.

Always verify the actual terminal layout of the switch before wiring, as pin arrangement can vary between product versions.

Product Disclaimer

Product specifications may vary between manufacturers and production batches. Please verify the actual switch rating, terminal layout, and dimensions before installation.

Product images are for illustrative purposes only and may differ from the actual product in colour, finish, or appearance.

Important Note

Current Rating

Do not exceed the switch’s rated voltage or current. Motor startup and stall currents can be significantly higher than normal operating current.

Wiring Safety

Disconnect the power supply before wiring or modifying the circuit. Confirm the terminal configuration before applying power.
