Snap Action, Limit Switches

1SE401 are snap action, limit switches which are widely used in a variety of applications from simple industrial automation to complex building management systems. These switches can be used to detect and measure the physical position or displacement of an object in a system, and are also used to start and control electro-mechanical processes.

Application Field

1SE401 are widely used in both industrial and commercial applications, such as the following:

• Industrial automation systems
• HVAC systems
• Lighting systems
• Security systems
• Automatic gates and doors
• Building automation systems

In addition to their diverse application fields, these switches are also used by machine shop tools, medical devices and laboratory equipment.

Working Principle

1SE401 switches offer two types of operation: momentary contact and latching contact. When the switch is actuated, its contacts open and close rapidly, creating brief pulses of current. These pulses are used to signal the presence or absence of an object in the system, or the momentary position of an object in the system. By combining multiple switches in different mechanical configurations, the displacement and position of objects in the system can be measured.

These switches can also be used to start and control electro-mechanical processes. When actuated, the switch will start the process, and when the switch is released, the process is terminated. This type of operation is often used in industrial automation systems, where the switches are used to manipulate high-speed machinery in a safe and efficient manner.

1SE401 switches are also known for their high reliability and long service life. The contact area of the switch is made from a durable material, which ensures that the switch will last for many years with minimal maintenance or repair.

In summary, 1SE401 snap action, limit switches are widely used in a variety of applications and offer reliable performance. They are able to detect and measure the physical position or displacement of an object in a system, as well as to start and control electro-mechanical processes.
