Snap Action, Limit Switches

Snap Action, Limit Switches are switches which provide electrical protection against changing currents, voltages and temperatures. The LSN5A switch is designed to provide reliable protection from overheating and other damages caused by fluctuating temperatures and current levels. This switch is designed to open and close electrical circuits when ambient temperatures cross predetermined thresholds.

The LSN5A consists of two main parts: the main body and the actuator. The main body, which is typically mounted in a fixed place, includes an electrical contact spring, a mounting stem, and a pressure valve. The actuator, which attaches to the main body, is composed of a curved arm and a plunger assembly that is responsive to changes in temperature and current levels. When power is applied to the switch, the actuator arm rotates and the plunger assembly fires a metallic snap element, which trips the contact spring open. This interrupts the circuit, cutting off power. When the temperature drops or the current levels fall, the arm rotates back, pulling the plunger assembly back and resetting the switch.

The primary benefit of the LSN5A is its ability to provide reliable protection from temperature and current levels that may cause damage to electrical equipment. This switch can be used for a variety of applications, including temperature control for medical devices, safety switches for gas lines, power management for HVAC systems, industrial machines, and other systems that require precise temperature regulation.

The LSN5A switch is typically wired in series, so that each component on the circuit is individually protected from potential harm caused by temperature and current fluctuations. This also reduces maintenance costs, as the switch can easily be disconnected and tested to verify its operation condition. As a result, the switch can be used on devices that require frequent testing and adjustment or on applications that require protection from frequent temperature and voltage changes.

When it comes to installation, the LSN5A is one of the most user-friendly switches on the market. It requires minimal wiring, and the switch can be quickly attached and detached by a simple locking mechanism. The plunger requires only a small amount of movement to reset the switch, making it ideal for use in tight spaces where frequent adjustment would be impossible. Additionally, the switch is designed to be mounted in both horizontal and vertical configurations, allowing for multiple installation options.

The LSN5A switch is an excellent choice for applications where precise temperature regulation is required. Its ability to protect electrical equipment from overheating, current levels, and temperatures makes it ideal for a variety of uses. Its user-friendly design and quick reset time make it an ideal choice for tight spaces or applications that require frequent testing and adjustment.
