The main switch is the cornerstone of every circuit. Its function is to disconnect the machine and all electrical connections from the mains during cleaning, maintenance and repair, as well as when the machines are idle for long periods. It must comply with IEC/EN 60947-3 for user category AC23.

The position of the main switch shall be clearly indicated, either by a visible separation of the contacts (open position) or by a clear indication of the position. The main switch shall also be capable of being locked in the “Off” position to allow safe servicing. The switch may also be used as an emergency switch but must then be properly marked with a red handle on a yellow background.

Main (service) or emergency stop switches are available in a variety of mounting options, allowing a wide range of applications with rated currents from 10A to 125A. Switches can be three or four pole or, on special order, multi-pole and equipped with auxiliary contacts if required.

These switches are used for installation in control cabinets and distribution boards to control process variables in various buildings (residential and commercial buildings, hospitals, production halls, etc.).

They also allow direct control and operation of simpler machines or devices. Compact switches with different functionalities and rated current up to 10A are designed to enable the realization of applications for the control of various processes.

The ridge switches are available in different mounting options, allowing a wide range of applications with rated currents from 10A to 125A. The switches can be single or multi-pole and equipped with auxiliary contacts if required. They can also have a different number of positions depending on the requirements.
