D3V-166M-3C5

Application Field
The D3V-166M-3C5 is a heavy-duty switch specifically designed to provide robust performance and durability under a range of different application scenarios. It is suitable for applications in the automotive, industrial, and HVAC sectors, as well as in applications with mercury-free environments. The switch is housed in a plastic enclosure, and its robust construction is designed to resist most common threats to its operability, including dust, water, and vibrations. The switch has contacts rated at 20 amps, which makes it suitable for situations needing a robust power switch.

Working Principle
The D3V-166M-3C5 is designed as a momentary switch, meaning that it closes when pressing its actuator, and opens when releasing it. The switch is designed using snap-action principles, in which the actuator is equipped with a snap-action mechanism. This mechanism allows for precise and fast operations, with reliable contacts and repeatable operations. The contacts are made from silver, and the terminals from copper, making them resistant to corrosion and offering increased durability. The switch incorporates two contacts and is available in normally open and normally closed configurations, allowing for versatile applications.

In Summary
The D3V-166M-3C5 is an example of a snap-action, limit switch that is suitable for a range of applications. Its robust design and construction, and its momentary design with snap-action principles, make it an ideal choice for applications needing reliable and durable operation. With its contacts rated at 20 amps, it is capable of handling high power applications, and its two contacts allow for versatile operation. Finally, its corrosion-resistant silver contacts and copper terminals offer increased durability and long-term reliable performance.
