Snap Action, Limit Switches: 44542-2120 Application Field and Working Principle

A snap action switch, also known as a snap switch, is an electrical component that allows for electric energy to flow in and out of a circuit. This type of switch primarily operates by sending a signal which tells an component to turn on or off.Snap action, limit switches are designed to monitor and limit the movements of machines or the positions of objects. They are often used in industrial and automation tasks to control the engagement of moving parts in a process. The specific product discussed in this article is the 44542-2120 snap action/limit switch.

The 44542-2120 has extended service and a heavy duty housing. Its design includes a corrosive resistant nickel plated housing, a 1/2 enameled wire lead and a precision M8 nut with companion spacer. Its contact current carrying capacity is up to 10A, the Terminal Contact capacity is up to 14A and it has a voltage rating of up to 250 Vac. This product is a momentary, single pole, double throw switch and has three positions, normally open, normally closed and simple make/ break (on/off).

The 44542-2120 snap action/limit switch is commonly used for positioning and controlling, verification, security and detection applications. These switches are usually installed in automated machine tools, conveyor systems, metering systems, door locks and liquid level sensors.

The working principle of the 44542-2120 switch is quite simple. The switch contains two separate switches that are connected in series with a contact body suspended between them. When pressure is applied to the contact body, it will become energized and will cause the two switches to close or open, respectively. By doing so, the switch allows electricity to flow in or out of the circuit.

Some of the features of the 44542-2120 switch that make it a good choice for many tasks include its extended service life, adjustable actuation force, adjustable plunger travel and its robust construction. Additionally, the 44542-2120 is fully enclosed, making it dust and water proof which makes it suitable for both indoor and outdoor use.

Despite its simplicity, the 44542-2120 snap action/limit switch makes an important contribution to the security, reliability and accuracy of a variety of automated applications. As such, it has become a popular choice for a wide range of projects. With its resilient construction and long service life, it is likely to remain a popular option for many years to come.
