21EN278-6

Snap action, limit switches are versatile electrical switches used in a wide variety of applications and environments. These switches are particularly suitable for applications where a single switch is required to accurately control the operation of a machine or process. The 21EN278-6 snap action, limit switch is a single pole, normally open, momentary contact switch. This switch has a single set screw, which can be used to adjust the position of the switch contacts, allowing the contacts to switch on and off in a variety of positions. This is an important feature, as it allows for precise, repeatable control over a wide range of applications.

The working principle of this snap-action, limit switch is fairly simple. The switch contains two sets of contacts, usually made of metal, which are connected to two metal bars. These bars are activated by a lever, which pushes the bars against each other when the switch is activated. This creates an electrical connection between the two sets of contacts, thus allowing a current to flow. When the switch is activated, the lever pushes the bars together, creating an electrical circuit. When the switch is deactivated, the lever is released, allowing the two bars to separate, breaking the electrical circuit and preventing the current from flowing.

The 21EN278-6 snap action, limit switch is capable of switching on and off in a wide range of applications, due to its adjustable contact positions and repeatable performance. This switch is commonly used for controlling industrial machinery, controlling the flow of electrical current, safety applications, and detecting the position of moving objects. In addition, these switches are often used as emergency stop buttons, allowing operators to quickly stop a machine or process in the event of an emergency or fault.

The 21EN278-6 snap action, limit switch is a reliable and durable switch, due to its robust design and high quality materials. The switch is rated for up to 500,000 operations, and has a maximum voltage rating of 48 Vdc and a maximum current rating of 6 Amps. This makes the switch suitable for many applications.

In summary, the 21EN278-6 snap action, limit switch is a versatile and reliable switch, which is well suited for a wide range of applications. This switch is capable of switching on and off in a variety of positions, and has a high electrical rating, making it suitable for many industrial and safety applications.
