3 Pin Toggle Switch-Pack of 5:

A 3-pin toggle switch is a type of electrical switch commonly used in various applications to control the flow of electricity. Here's a brief description of its components and how it works:

1. Toggle Mechanism: The toggle switch gets its name from the small lever, known as the toggle, which is used to manually operate the switch. This lever can be moved back and forth between two or more positions to open or close the circuit.

2. Pin Configuration: A 3-pin toggle switch typically has three metal pins or terminals extending from its body. These pins are used to connect the switch to an electrical circuit.

   • Common (COM) Pin: This pin is the central pin and is usually connected to the power source or the load, depending on the circuit configuration.

   • Normally Open (NO) Pin: This pin is connected to the common pin when the switch is in its default position (usually the "off" position). When the switch is toggled, the connection between the common and normally open pins is broken.

   • Normally Closed (NC) Pin: This pin is connected to the common pin when the switch is in its default position. When the switch is toggled, the connection between the common and normally closed pins is broken.

3. Functionality: Depending on the circuit's requirements, the 3-pin toggle switch can be used as a single-pole, single-throw (SPST) switch, where it simply opens and closes a single circuit, or it can be used in more complex configurations like single-pole, double-throw (SPDT) or double-pole, double-throw (DPDT) switches, allowing it to control multiple circuits or change the connection between circuits.

4. Applications: 3-pin toggle switches are commonly found in a variety of electronic devices, appliances, control panels, and machinery where manual control of electrical circuits is needed. They're often used in situations where it's necessary to physically switch power on or off, such as in lamps, fans, motors, and other similar devices.
