The 3-Pin SPDT Mini Toggle Switch is a reliable and tactile solution for controlling power in small-scale electronics. At Electrapac, we recommend this switch for makers and students in Bangladesh who are building projects that require a simple, high-quality way to toggle between two states or safely cut power to a circuit.

This is a Single Pole Double Throw (SPDT) switch, which means it has one common input pin and two output pins. It can be used as a standard ON-OFF switch by using only two pins, or as an ON-ON selector switch to toggle power between two different components (like switching between a Green LED and a Red LED). Its compact size makes it perfect for mounting on custom control panels, robot chassis, or handheld enclosures.

Key Features for Electrapac Customers

• Durable Bat Handle: The chrome-plated metal lever provides a crisp, satisfying "click" that confirms the switch has moved, even when wearing gloves or working in the dark.

• Versatile Power Ratings: Rated for both 125V and 250V AC, this switch is robust enough for household appliances yet sensitive enough for low-voltage 5V/12V DC hobby projects.

• Secure Panel Mounting: Comes with a hex nut and a locking washer, ensuring the switch stays firmly in place without spinning when you flip the lever.

• High-Quality Solder Lugs: The three pins feature pre-drilled holes, making it easy to loop your wire through before soldering for a rock-solid electrical connection.

• Heat-Resistant Body: The base is constructed from high-temperature phenolic resin, preventing the housing from melting during the soldering process.

Understanding the 3-pin layout is key to using this Electrapac switch correctly:

1. Center Pin (Common): This is where you connect your incoming power source.

2. Side Pins (L1 / L2):

   • As an ON-OFF Switch: Connect your device to the center pin and one of the side pins. Leave the third pin empty.

   • As an ON-ON Selector: Connect the center pin to power, and connect two different devices to the two side pins. Flipping the switch will turn one off while turning the other on.

3. Mounting: Use a 6mm drill bit to create the hole in your panel. Sandwich the panel between the two nuts for a professional, flush finish.

Pro-Tip: If you are using this switch for a 220V AC application, always use Heat Shrink Tubing over the soldered pins to prevent accidental short circuits or electrical shocks.

• DIY Projects: Main power switches for Arduino, ESP32, and Raspberry Pi prototypes.

• Audio Equipment: Toggling between different audio inputs or turning internal amplifiers on and off.

• Model Railroading: Controlling track power or switching signal lights between Red and Green.

• Automotive Accessories: Controlling low-draw interior lights or cooling fans in cars and vans.

• Home Automation: Manual override switches for smart lighting or gate control systems.

We source our Mini Toggle Switches with reinforced internal contacts to ensure they can handle thousands of cycles without losing their "click" or electrical conductivity. Visit us at www.electrapac.com for the essential hardware that gives you total control over your tech.
