V7-7B19D8-263 Datasheet/PDFSnap action, limit switches are a type of electro-mechanical device used to sense the position of an object. The V7-7B19D8-263 is a particular type of snap switch which is ideally suited for a variety of applications. This article examines this switch and its features, providing an overview of its construction, application field and working principle.
Construction
The V7-7B19D8-263 snap switch is designed as a single-pole, single-throw (SPST) switch. It has an integrated contact seal, which ensures protection against dust and contaminants. Additionally, it is made from a durable stainless steel design to be able to withstand a wide range of temperatures, from -55°C up to 125°C. The V7-7B19D8-263 switch is very compact in design, with an overall size of only 55mm x 16mm x 15mm.
Application Field
Due to its compact design and strong construction, the V7-7B19D8-263 snap switch is suitable for a range of applications, including limited switch-on/switch-off operations, limit sensing, and level detection. Additionally, due to its resistance to extreme temperatures, this switch can be used in environments with high temperature changes, such as aerospace applications.
Working Principle
The V7-7B19D8-263 snap switch works on the principle of momentary contact. The contacts open and close momentarily when a change in the mechanical strength is detected, thus closing or opening the circuit. The contacts are silver-plated to provide a good electrical connection, and the switch is sealed to protect against dust and contaminants. When the force is removed, the contacts re-open and the circuit is opened again. The switch can be operated manually or via an external circuit.
Conclusion
The V7-7B19D8-263 switch is a small, robust and reliable solution for limited switch-on/switch-off operations, level sensing, and other similar applications. Its small design makes it suitable for tight spaces, and its resistance to extreme temperatures makes it suitable for aerospace applications. Its momentary contact principle ensures reliable operations, making this an ideal choice for a wide range of applications.
