Snap Action, Limit Switches: LZL1 Application Field and Working Principle

Snap Action, Limit Switches, also known as LZL1, is a type of electromechanical switch which operates when an external force is applied. Its purpose is to interrupt or establish a circuit in a device or system. A limit switch is actuated when a movable contact is positioned near a stationary contact or when the metered force is applied to the movable contact. The mechanical action of an actuating force is used to provide a connection between the contacts, and this contact action is then used to control an electrical circuit.

At its most basic level, LZL1 operates on a single or double metal contact switch, which interlocks to form an electrical connection. As the metal contact switch closes, the electrical current is allowed to flow through the metal contact switch and complete the circuit. The operating temperature of the metal contact switch can range from -40 to 105 °C. The electrical resistance of the metal contact switch is between 50m and 600m Ω. This metal contact switch is contained within an enclosure, often made from high-grade plastic, metal, copper or stainless steel.

LZL1 switches are typically found in applications such as motor control and automation, electrical wiring systems, security systems, conveyor systems, HVAC systems, and industrial machinery. The switches can be used to perform simple on/off operations, or more complex operations involving multiple, multi-positioned contacts with varying amounts of force. LZL1 switches can also be used to control multiple devices or systems, such as a machine containing several axes. This makes them ideal for use in many industrial and commercial applications.

The working principle of LZL1 is based on the principle of mechanical action to provide a connection between the contacts. When the switch is actuated with the help of an external force, the movable contact moves and then comes in contact with a stationary contact. This creates an electrical connection between the two contacts, which can be used to control the circuit. The return spring then releases the movable contact, breaking the connection and resetting the switch.

Overall, LZL1 is a reliable choice for a variety of applications that require either a simple on/off control or a more complex operation involving multiple points of contact. In most cases, LZL1 switches can be supplied as plug-in modules, allowing for a quick and easy installation.
