Snap Action, Limit Switches: 6LS2 application field and working principle

Snap-action limit switches (6LS2) are widely used as an electrical control and automation in a large range of industrial and consumer applications. They are designed to detect and act on mechanical movement, pressure, and temperature differences. The working principle of 6LS2 limit switches is fairly simple; when a mechanical force or pressure activates the trigger, it causes the actuator arm to move, which triggers a limit switch that either opens or closes a circuit. This opening or closing of the circuit produces an electrical contact and signals a change in the electrical current.

6LS2 snap-action limit switches are available in a variety of mechanical and electrical configurations, making them suitable for a range of applications. In most cases, the snap-action switch is used to indicate when a transition from an off state to an on state has occurred or vice versa. This transition can be used to control a variety of devices, including motors, lights, pumps, and brakes.

Typical 6LS2 applications include door and window open/close detection, level sensing systems, open/close logic in machinery, access control systems, and many more. In some industrial settings, these limit switches are used to control safety-critical functions and processes. For example, a 6LS2 switch can be used to shut off a machine when an overload is detected, or to ensure safe operation when used in conjunction with other safety features.

The 6LS2 limit switch works by using a contact system consisting of two parts: an actuator arm and a contact block. The actuator arm is a small lever connected to the contact block, which contains two electrical contact points. As the actuator arm moves, it causes the two contact points to open or close. Once this happens, a current change is delivered to the external circuit.

In some designs, the actuator arm houses a “snap-action” element. This element is designed to create a sharp, momentary change in contact pressure when the pressure applied to the switch reaches a certain level, causing the contacts to open or close. This element allows the switch to react quickly and have a longer life due to the short duration of contact.

The 6LS2 limit switch is used in both single circuit and dual circuit systems. In a single circuit setup, a single contact block is used and the switch is activated by applying pressure to the actuator arm. In a dual circuit setup, two contact blocks are used and the switch is activated by pressing both activator arms simultaneously. This setup has the advantage of being able to detect when two independent devices are being used in the same system.

Overall, the 6LS2 snap-action limit switch is a versatile device capable of providing reliable and accurate control and automation in a wide range of industrial and consumer applications. The switch’s ability to quickly detect and switch a circuit, as well as its long life expectancy and compact design, make it ideal for use in tight spaces, in systems protecting against overload, and in numerous other applications.
