2.1 General
The application of this specification is focused on the utilization of TACT Switch in electronic devices. It is essential to generate content that closely resembles the original text while ensuring that the information provided remains the same.
2.1.2 Operating temperature range -20℃ ～ +70℃
The temperature range for storage is -30°C to +80°C. Make sure to keep the items within this temperature range for optimal storage conditions.
Let's discuss the test conditions for a moment. To ensure accurate and consistent results, it's important that we establish specific parameters and criteria before conducting any experiments. These conditions may include factors such as timing, temperature, equipment, and other variables that could impact the outcome of our tests. By carefully controlling these elements, we can create a controlled testing environment that eliminates extraneous influences and allows us to gather reliable data. It's crucial that we pay close attention to these test conditions in order to achieve meaningful and trustworthy results.
Ambient temperature 5~35℃
Relative humidity 45~85%
Air pressure 86~106kPa (860~1060 mbar)
In case of any discrepancy in the verdict, certain tests will be carried out under specific circumstances. The objective of these tests is to alleviate any doubts and ensure clarity of the outcome.

2.2 Appearance construction and dimensions
The Appearance Switch must be free from any signs of wear and tear, rust, cracks, or plating defects, and should have a smooth and polished surface.
When it comes to construction and dimensions, it is essential that you refer to each individual product drawing for accuracy and specific details. These drawings will provide you with a comprehensive understanding of the product's overall structure, how it is put together, and all of its dimensions. By reviewing these drawings, you will be able to identify any critical information about the product that you need to know, such as its weight, height, width, or depth. It is important to keep in mind that every product is unique, and therefore, its construction and dimensions will vary based on its design and purpose. Therefore, it is crucial to take the time to review the product drawings carefully to ensure that you have a solid understanding of the item's features and specifications.
