Working under voltage is prohibited in the interests of safety as there is a risk of electric shock. Additionally, connecting a switch to a voltage source can cause damage to internal electronic components due to unexpected power surges, which can ultimately cause the device to malfunction or break.

It is important to emphasize that following the prohibition against live work will also help reduce the risk of fire or short circuit in the electrical system. The electronic components of the switch are extremely sensitive to voltage changes, and their damage can lead not only to failures in the device itself, but also to unpredictable consequences for the entire electrical network. Therefore, strict adherence to safety rules when working with electrical equipment is necessary to maintain reliable and safe operation of electrical systems.
