Snap Action, Limit Switches: WLGCA2-LDS-M1GJ-1-N Application Field and Working Principle

Snap-action limit switches are a type of switch whose contacts change state with a distinct and noticeable movement when a fixed amount of mechanical force is applied. Generally, snap-action limit switches are categorized into categories such as basic switches, proximity switches and position switches. In particular, the WLGCA2-LDS-M1GJ-1-N snap-action limit switch is well-suited for applications requiring reliable and cost effective mechanical life.

The application field of the WLGCA2-LDS-M1GJ-1-N snap-action limit switch consists of a wide range of applications, such as automated manufacturing equipment, home appliance, aerospace, pumps and valves, and power generation equipment. For instance, in automated manufacturing equipment, the WLGCA2-LDS-M1GJ-1-N switch is effective in detecting the positioning of a specific part and thereby controlling the machinery\'s operation. Similarly, in pumps and valves, the WLGCA2-LDS-M1GJ-1-N switch functions as a limit switch that can detect the upper or lower limit of a valve stem\'s movement and prevent overload or shut the pump off in irregular cases. On the other hand, in home appliances, the WLGCA2-LDS-M1GJ-1-N switch may be used to detect the open or closed position of a timer, thereby controlling the timing of an appliance. These examples demonstrate the broad range of applications for which the WLGCA2-LDS-M1GJ-1-N switch is suitable.

Upon the application of an external force, the WLGCA2-LDS-M1GJ-1-N snap-action limit switch operates through the combination of two mechanisms, contact bouncing and snap action. In contact bouncing, when an external force is applied to the actuator, the contact bounces multiple times in the off state prior to breaking contact. This mechanism effectively prevents the contact from weld burning, thereby permitting stable switching action. Having a short operating time, the contact bouncing mechanism results in a noticeably reduced amount of wear and tear. In the snap action mechanism, a cam attached to a diaphragm spring enables fast switch movement. When the tension of the diaphragm spring is exceeded, upon the application of external force, the cam overcomes the spring\'s tension and abruptly jumps to the contact, causing the snap action to occur. Unlike contact bouncing, the snap action mechanism is relatively noisy, resulting in audible clicks.

The WLGCA2-LDS-M1GJ-1-N snap-action limit switch has passed a qualified 0.1 million operations test, thereby providing users with a long mechanical life of 19.2 million operations. The product is also waterproof with an IP67 protection level, enabling it to be safely used in a wide range of environments. Additionally, the product has an ultra-miniature design and requires a low panel cutout of 4mm. With these characteristics, the WLGCA2-LDS-M1GJ-1-N snap-action limit switch is a cost effective product that can be used in a wide array of applications.
