Toggle SwitchesToggle switches are one of the most commonly used switch styles and can be found on many different types of electrical applications. At SHOUHAN, we offer a wide variety of toggle switches in a range of sizes and characteristics to accommodate many different application types. The toggle switch selection below can fulfill the requirements of many automotive, marine, and industrial type applications, along with a wide spectrum of general or custom electrical applications. Choosing the correct toggle switch for your application is subject to the rating and specifications of the application and the switch chosen. A variety of actuations are available to choose from to ensure your application functions as desired. The actuation circuits available include Single Pole Single Throw (SPST), Single Pole Double Throw (SPDT), Double Pole Single Throw (DPST), and Double Pole Double Throw (DPDT). Specialty actuations are also available including 3PDT, 4PST, and 4PDT. Most actuation circuits come with a momentary actuation option, indicated by ( ). Some of the toggle switches can also be found with illuminated options. Illuminations vary by each style, but many of the toggle switches feature red, blue, green, white, or amber illumination for clarity of the switch actuation along with a clean and professional look to your application. Along with actuation options and illumination styles, the toggle switches feature varying handle shapes and termination types depending on the demands of your application. Some of these handle shapes include standard, short, wedge, and duckbill. The termination types of the toggle switches available include screw, flat, and push-on terminations. From heavy-duty to sealed and plastic, SHOUHAN offers a variety of toggle switch styles to give your application the desired look and function.

Therefore, we get two outputs, one from COM and A and second is from COM and B, but only one at a time. Mainly it is used in three-way circuit to turn ON/OFF an electrical appliance from two location.
How to Use Toggle Switch?In the circuit below, the first and second output of are connected to the lamp and motor respectively. Initially, the lamp will glow and motor remain in OFF condition as shown in the circuit. When we toggle the switch the motor turns ON and lamp turns into OFF condition. So, we can control two loads from a single switch.
This switch mainly used in making three way switching circuit for the staircase in the homes. Also, for normally controlling loads.
