The operation of the safety switch is based on the calculation of the difference in current in the circuit, so that if this difference exceeds a certain limit, it indicates a leakage current and cuts the circuit. This switch is available in different types from 25 to 63 amps with a sensitivity of 30 or 300 milliamps. In addition to preventing electric shocks, this switch is also used to prevent fires caused by leakage current. **[Click here to view LS products.](https://www.automation24.ir/product/list/search?keywords=&in_description=1&category_id=0&inc_subs=1&manufacturer_id=24&pfrom=&pto=)** ## The sensitivity of life-saving keys is selected according to the type of protection: - Human protection against direct contact: 6, 10 and 30 mA are usually considered. But due to the frequent interruption of the circuit during the occurrence of leakage currents of 6 and 10 mA, the most sensitive used is 30 mA. - Human protection against indirect contact: 300 and 500 milliamps are usually considered. These types of parts are mandatory in TT systems and recommended for lateral safety in TN and IT systems. - Protection of equipment against the risk of fire: 300 mA is usually considered.

There are many push buttons in the market with different models and different shapes and mechanisms. Push buttons actually perform a function when pressed by the operator. Push buttons can be momentary, that is, they act as soon as we press it and it returns to its original state if we let go of it, or it can act in such a way that it acts by pressing it and in It remains in the same position and returns to its first position by being compressed again.\r\n\r\n\r\n\r\nPush buttons in terms of color:\r\n\r\nPush buttons are also made in different colors, each of these colors represents a type of function. For example, red color is used to step the system and green color is used to start or start the car. This feature prevents the operator from making mistakes while working with these keys.\r\n\r\nAlso, a series of push buttons in red color have bigger heads than other push buttons, which are called mushroom keys in the industry and are used as emergency chassis in the system. This type of mushroom push buttons is designed in two ways, with keys and simple, for use in different places.
