Snap action, limit switches are electromechanical devices used to sense and control the movement of objects. These switches can both detect the position of an object, as well as actuate mechanisms. The 21SX39-T is one type of snap action, limit switch. It is available in a wide range of sizes, configurations and contact options, allowing it to be used in a variety of applications and operating conditions.

The 21SX39-T uses a snap-action mechanism to create a reliable, long lasting switch. A small amount of force is applied to the actuator, causing it to quickly snap into its ON or OFF position. This type of switch is designed for quick action and is often referred to as a \'snap\' switch.

The 21SX39-T is designed to open or close electrical contacts when a specific force is applied. This switch is often used to activate a circuit when the switch is actuated. Its applications include machine control and industrial equipment, such as energy saving systems and HVAC systems. The 21SX39-T can also be used as a safety device, preventing the machinery from running when no operator is present.

The 21SX39-T is available with two different types of contacts: momentary and maintained. Momentary contact switches are used when a circuit needs to be enabled for a brief period of time, while maintained contact switches are designed to keep a circuit enabled until the switch is actuated again.

The 21SX39-T has several mounting options. These include mounting brackets from a variety of manufacturers, as well as screw and rail mounting. This allows the switch to be used in the exact application it was designed for. It is also available in custom configurations to meet specific application requirements.

The 21SX39-T is compatible with a variety of circuits, including AC, DC and low voltage systems. It is available in several contact options, including three and fourpole versions, with a variety of contact ratings. The contact material used in the 21SX39-T is generally silver alloy, although other materials can be used upon request.

In addition to its various contact options, the 21SX39-T is also available with optional features such as: sealants, locknuts and mounting components. These features come in a variety of options and can be selected to suit the application environment and the customer\'s specific requirements. This allows the customer to customise the switch to their specific needs.

The 21SX39-T has a wide variety of uses, ranging from machine control to safety devices. It is reliable, long-lasting and available in a range of sizes, configurations, contact options and mounting types. This allows it to be used in the exact application it was designed for, providing the customer with a flexible and efficient solution.
