Snap Action Limit Switches

The WL01NJ-2 is a type of Snap Action limit switch, which is used to quickly actuate and shut off electrical circuits in domestic, industrial and automotive applications. A limit switch consists of a lever — actuated by the mechanical movement of a machine or process — connected to a set of electrical contacts that open or close when the lever is moved. In this way, the switch can be used to both detect the presence and/or movement of an object, as well as to control electrical systems.

The WL01NJ-2 is a subminiature limit switch with a contact configuration of 1N/O (1 normally open) and 1N/C (1 normally closed). It has an operating travel of 0.7 - 1mm, a mechanical life of 10,000 cycles, and operating temperature range of -25°C to 70°C. Other features include a positive opening contact, wired LED indicators for status indication and a firm snap action that can be maintained over long periods of time.

The working principle of the WL01NJ-2 is fairly simple; when the lever is pressed, the contacts within the switch open or close, depending on the contact configuration of the switch (normally open or normally closed). This allows an electrical circuit to be opened or closed, simply by pressing the lever. Depending on the type of limit switch, the lever can be either manually pressed or actuated by another device or machinery feature, such as a machine shaft.

When taken at face value, the WL01NJ-2 is an impressively powerful device. It is small, but nevertheless capable of switching currents of up to 5A at a voltage range of 250V AC/DC. It is also a durable piece of machinery, thanks to its robust construction, stainless steel cover and ceramic plunger that stands up to frequent use. More importantly, its snap action make it extremely reliable, ensuring a positive and consistent performance across a wide range of industrial and automotive applications.

In summary, the WL01NJ-2 is a reliable and efficient snap action, limit switch that is ideal for applications that require a device capable of quickly and reliably actuating and shutting off electrical circuits. Whether used to detect the presence and/or movement of an object, or to control complex electrical systems, the WL01NJ-2 is a must-have device in any industrial, domestic or automotive setting.
