Snap Action, Limit Switches

A snap action, limit switch is an electronic switching device designed to detect the presence of an electrical current. The switch is usually installed within an electrical device and it is designed to provide reliable switching and protect the device from any type of interference or damage caused by electrical current. The switch can also be used to detect the positions of other objects, or to control the speed of a motor or other electrical device.The VB-2251 snap action, limit switch is a popular model of snap action switch used in various applications. It is a single-pole, single-throw (SPST) switch. The VB-2251 switch can operate in a variety of positions, including toggle, momentary and intermediate. The switch also has a built-in adjustable current setting and has an adjustable pressure range of 0.6-8.7 bars.The VB-2251 limit switch is mainly used to control and manage two-wire circuits. This means that when a certain current is detected, the switch will instantly open or close, depending on the circuit. This switching action is known as a snap-action, or momentary switch, as it will only remain closed or open for as long as it is subjected to the electrical current. The VB-2251 switch is also often used to detect changes in speed, pressure, or temperature and provide a response based on the changes.The working principle of the VB-2251 limit switch is quite simple. The switch consists of two metal contact plates, known as actuators, which are connected together by a pair of pivot pins. When the actuators come into contact, the current flows through them and the switch is triggered, causing it to open or close. The switch can be adjusted to different current levels, so it can be used to detect small changes in current and still remain reliable. When the switch is closed, it will remain in the closed position until the current drops, or the switch is externally opened.Snap action, limit switches are commonly used in a variety of industries, ranging from industrial automation and process control to consumer electronics. The VB-2251 limit switch is especially popular due to its simple construction, reliable switching, and adjustable current settings. It is even used in robotic applications, where it can be used to detect and count objects, as well as monitor and control processes.In conclusion, the VB-2251 limit switch is an essential tool for many applications, and its reliable switching and adjustable current settings make it a popular choice among engineers. The switch is also affordable and easy to use, which makes it an ideal choice for a variety of applications.
