A toggle switch is an electronic component commonly used to control the on/off function of a circuit. It has a handle that can be switched between two or more positions, with each position corresponding to a specific circuit state. When the handle is switched to a position, the switch changes the way the circuit is connected, thus controlling the flow of current or signal in the circuit.
An on/off toggle switch typically refers to a Single Pole Single Throw (SPST) switch, which has two pins or terminals used for connecting or disconnecting a circuit. In its simplest form, a toggle switch is a mechanical switch operated by a lever or toggle, which moves up and down to open or close the connection between two circuits.
When the switch is in the “on” position, the circuit is closed, and current can flow through the switch. When the switch is in the “off” position, the circuit is open, and current cannot flow through the switch. This type of switch is commonly used in various electronic and electrical applications. Toggle switches play an important role in electronic and electrical engineering, and they can be used to control the switching of circuits, select between different circuits, adjust circuit parameters, and more. With the continuous development of technology, the types and functions of toggle switches are constantly increasing to meet the changing market demands.
