Snap action, limit switches, is a group of electromechanical devices which use polarized solenoids to make and break contacts as a means to activate alarms, motors, and a variety of other applications. The configuration of the switch, working principle, and function vary according to the application.

Types of Snap Action Limit Switches

Snap action limit switches come in a range of types, including basic and sealed configurations, contact configurations, and power switching capabilities.

• Basic Switches - These are the most common type of switch, providing a reliable and simple means of applying or breaking an electrical circuit. They are suited to applications where durability and functionality are the primary concerns.
• Sealed Switches - These switches can be exposed to the elements and last much longer than traditional switches. They are usually used in harsh environments.
• Contact Switches - These switches combine mechanical and electrical contacts in the same switch. The contacts may be preloaded for reliable operation over time, or configured for a specific application.
• Power Switching Switches - These switches are designed to switch larger currents or voltages. They are used in higher power applications, such as motors or pumps.

83265843 Application Field and Working Principle

The 83265843 snap action limit switch is a two-pole, UL-listed switch used in applications up to 600VAC. It features a one-piece design with a snap-on switch face, providing two independent switching points that are normally closed and open. The switch has a mechanical travel of 1.3mm (0.052 inch) and a contact rating of 10A at 128VAC.

The switch is operated by a magnetically polarized solenoid that is activated by current being applied to the stationary coil. This creates a magnetic field which causes the switch to open or close, depending on the direction of the current. The switch has a wide range of applications, ranging from industrial controls and motor starters to lighting control.

Common Applications of Snap Action Limit Switches

Snap action limit switches are commonly used in industrial applications and motor control systems. They can be used in lieu of mechanical switches for applications where precision and accuracy are needed, as well as for applications where regular use could wear out a mechanical switch. These switches are often used in applications such as medical diagnostics equipment, conveyor systems, elevators, and agricultural machinery.

Advantages of Snap Action Limit Switches

Snap action limit switches are a reliable and economical choice for many applications. They feature accurate operation and rapid switching speeds, as well as the ability to withstand abuse and harsh environments. The size and weight of the switch are also advantageous, making them well-suited for applications where space is a concern. Additionally, these switches are available in a variety of switching modes, making them suitable for different types of applications.

Disadvantages of Snap Action Limit Switches

While snap action limit switches are a reliable and economical choice, they are not suitable for all applications. The cost of the switch is slightly higher than that of typical electromechanical switches, and they require more space than smaller switches. Additionally, they may require periodic maintenance in order to remain in proper working condition.
