Toggle switches are commonly found in everyday objects, such as lights, appliances, and electronics. A toggle switch is a type of switch that is actuated by a toggle lever or button when connected to a power source. Toggle switches can also be used as a type of monitoring system or as an input device for a circuit or process control such as in industrial automation, where it may connect to a limit switch and relay. Toggle switches are created from several materials including metal, plastic, and fiberglass.

The WT21L toggle switch is a single pole single throw (SPST) type switch which is normally used as a on/off switch in industrial and control applications. It is reliable, dependable and rugged and is ideal for controlling low voltage and low current circuits. Available in a variety of sizes and configurations, this switch is a popular choice for use in commercial and residential applications.

The WT21L toggle switch is a momentary switch. When the switch is pressed, the switch will stay in the off position until it is released. When it is released, the switch will toggle to the on position. This type of switch is commonly used in control panel applications such as lights, air conditioners, and security systems.

The WT21L switch contains a bi-metal contact system which provides reliable contact action when the switch is actuated. The bi-metal contact system is designed to last for thousands of actuation cycles and withstand extreme environmental conditions including vibration and temperature changes. To ensure long life, the WT21L also features gold plated contacts and a protective enclosure.

The working principle of the WT21L toggle switch is simple. When the toggle switch is in the off position, the contacts are separated, preventing the flow of electrical current.
