What is a relay and how does it work?<\/h2>\n

A relay is an electromechanical device: a mechanism that is actuated by electric current. A relay can be compared to a switch with the difference that, instead of being operated manually, it is controlled automatically via a special circuit.<\/p>\n

Re.val.co International located in Rho, province of Milan, manufactures different types of relays, suitable for all types of use in both civil and industrial environments.<\/p>\n
