Snap Action Limit Switches are one of the most common types of switches used in a variety of industries, from manufacturing to transportation. The SZL-VL-H design is a particularly popular choice as it is highly versatile and suitable for a variety of applications. This article will discuss the application field and working principle of SZL-VL-H Snap Action Limit Switches.

SZL-VL-H Snap Action Limit Switches are primarily used in the manufacture and transportation of goods. The switch can be used to detect the position of objects and their speeds, as well as stop and start them upon a set limit. The limit of where the switch will be activated can be adjusted through its operation, making it ideal for use in a variety of settings and goods types. For example, they are used to stop the flow of gasoline in an automobile in the event of an emergency. They are also used in industrial settings to limit the speed of machines such as grinders, mixers, and saws.

On the technical side, the working principle of a SZL-VL-H Snap Action Limit Switch is based on two distinct parts: the static contact, which remains motionless in spite of the current, and the moving contact, which is operated by a mechanical or electric device. The static contact is connected to the main circuit, while the moving contact is connected to the switch’s control unit or a separate switch. A definite voltage is applied to the static contact and an indefinite voltage is applied to the moving contact. The current in the switch depends on the voltage applied to the static contact. When the limit, or set point, is reached, the voltage drop in the static contact will cause the moving contact to close the circuit and thus, the switch will be activated. This type of switch is especially useful for things such as controlling door locks and alarms in a home, or automating manufacturing processes.

The SZL-VL-H Snap Action Limit Switch is a very versatile and useful switch for a variety of applications. With its adjustable limit and high precision, it is a reliable and easy to use switch in both industrial and residential settings. This type of switch is also safe and reliable, providing peace of mind and long-term use. With all these features and benefits, the SZL-VL-H is one of the most popular choices for Snap Action Limit Switches.
