Snap Action, Limit Switches, also known as contactors, limit switches, or simply limiters, are designed to provide an accurate and reliable way of detecting the presence and movement of an object or material. They are used in many industries to provide safety, efficiency and control. The 21EN65-RB1 is an example of a snap-action, limit switch.

This switch is a 3-pin single-lock switch; the pins act as a mechanical linkage that sets off an electrical signal when the switch\'s mechanical lever is triggered. It has a normally closed configuration and is available in both SPDT and DPDT models. The maximum current carrying capacity of the switch is 15A, and it has a contact resistance of 50mΩ. It also has a mechanical travel of 2.5mm and an electrical travel of 1mm.

The 21EN65-RB1 switch is most commonly used in circuit board devices such as computer motherboards, switches, and thermostats. It is also used in industrial automation and control systems, including conveyor systems, sorting systems, robotics, security systems, vending machines, and door locks.

In a typical application, the switch is used to detect the movement or presence of an object. When a mechanical lever attached to the switch is engaged, it will trigger the switch, closing the contacts and generating an electrical signal. The signal can be used to trigger a mechanical switch, such as a motor or a servo, or to start a process, such as a robotic arm or a production line.

The 21EN65-RB1 is an incredibly versatile limit switch. Due to its small size, it can be used in handheld devices, such as doorbells, or in compact industrial control systems. Its compact design allows for it to be mounted almost anywhere, including tight spaces. Its low cost and reliable performance make it one of the most popular snap-action limit switches in the industry.

As with any electrical device, proper installation and maintenance of the 21EN65-RB1 is essential to ensure proper operation. It should be installed in a dust-free environment, and all contact surfaces should be regularly maintained and inspected. When replacing the switch, the proper wiring should be followed and connections should be checked for the correct polarity.

The 21EN65-RB1 is an efficient, reliable, and versatile snap-action limit switch. It is used in countless applications in many different industries, as it provides an accurate and reliable way of detecting the presence and movement of an object or material. With proper installation and maintenance, the switch will provide years of reliable service.
