Toggle Switch Question & AnswersMay 12, 2023 By Wat Electrical This article lists 50 Toggle Switch MCQs for engineering students. All the Toggle Switch Questions & Answers below include a hint and a link to the relevant topic wherever possible. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Toggle Switch.A toggle switch is an electrical switch that has two positions - on and off. It is called a toggle switch because it can be toggled or flipped between these two positions. When the switch is in the on position, it allows electrical current to flow through the circuit it is connected to. When it is in the off position, the circuit is broken, and no current can flow. Toggle switches are commonly used in a variety of electronic devices and electrical systems, including lighting fixtures, fans, appliances, and machinery. They come in various sizes and shapes, ranging from small switches used in handheld devices to large switches used in industrial equipment.Toggle switches can be either single pole single throw, single pole double throw, double pole single throw, or double pole double throw. The type of switch used depends on the specific application and the number of circuits that need to be controlled. The toggle switches can control lights, fans, AC and DC motors, pumps, and other electrical devicesToggle switches are typically easy to operate and have a long service life, making them a popular choice in many applications. They can be found in a wide range of sizes, from miniature switches used in electronics to larger switches used in industrial settings. 1). What is a toggle switch?
