Panel switches are electrical micro switch buttons that allow us to control and operate electrical appliances, machines, light and heavy equipment. They were created in order to provide us with safety and convenience when working in single-phase or three-phase electrical networks.
One of the most basic principles of panel switches is their function to break and restore an electrical connection. This means that when the switch is turned on, current flows through it and the electrical device works. Panel buttons, switches, play the role of an electric switch equipped with built-in contacts NO (normally open) or NC (normally closed) to control the power supply of electrical appliances in the industry, home or office.
It is important to note that panel switches are designed to be safe and prevent electrical accidents. They are equipped with special mechanisms that ensure that the current will be interrupted if an overload or short circuit occurs, which means that they protect us from electric shocks and fires that can be caused by unstable electrical connections.
Unlike ordinary pushbutton switches, panel switches are designed to be built into machines and are therefore almost standardized in terms of dimensions - typically ф12mm or ф22mm. Depending on the application, panel switches are available in different colors and shapes, two or three stable positions, LED light indication, key lock or other extras. Another important thing to consider when choosing a panel switch and the type of electrical appliance they will control is to consider the voltage and current they can handle. In the case of an incorrect panel switch that is not suitable for the load of the device, the machine or the electrical appliance, it may cause the switch to malfunction and, accordingly, it may not be possible to start or stop a facility, or to cause an accident.
