Snap action limit switches are electromechanical switch devices that are used for controlling and measuring various functions, such as speed, position, temperature, pressure, and current. These switches are basically mechanical in nature, with certain electrical contacts placed in the switch that switch on and off when a certain mechanical pressure is applied. The LSYAB4L-2A is a type of snap action limit switch, which can be used in a variety of applications.

The LSYAB4L-2A is actuated by a plunger-type operator that features stainless steel construction and a positive actuation force. This plunger is held in place by a spring which helps to prevent it from moving several times until released by the operator. When the plunger is released, the electrical contacts within the switch open or close, depending on the type and purpose of the switch. With the LSYAB4L-2A, both normally open and normally closed contacts are available and can be actuated from side or top.

The LSYAB4L-2A is commonly used in various applications including process control systems, anti-lock braking systems, switches for automotive instruments, and general limit switches for industrial and commercial applications. The limit switch is designed to withstand extreme temperature and humidity conditions, from -40°C to 105°C, while providing reliable and precise results. The switch is also vibration resistant, making it ideal for use in industrial and environmental conditions.

In regards to its working principle, the LSYAB4L-2A operates using a unique concept called “snap-action”. This concept involves the physical movement of the actuating element being released when it is physically moved by the operating force. As the switch contacts pass each other, they create an electrical contact that is triggered upon reaching a certain pressure. This triggers the electrical current to flow between the contacts, either opening or closing a circuit depending on the necessary usage.

The snap-action limit switch works in the same way as a push button on a light switch. When the button is pushed, the internal mechanism of the switch stays put until the force is strong enough to make the switch contacts move. The contacts then move and create the necessary electrical contact, opening or closing the circuit as needed. This is what the LSYAB4L-2A does, using its unique design and performance features.

Overall, the LSYAB4L-2A is a very useful and reliable type of snap action limit switch. Its robust construction and performance features make it an ideal choice for a variety of applications from automotive to industrial. The switch operates by the “snap-action” method, allowing it to be triggered upon reaching a certain pressure, creating a reliable electrical contact for a short period of time.
