What is a Contact switch?

A contact switch is a switch that controls signals with contacts such as pressure contact and electrical contact. Various products are produced depending on the contact method. It is a device that requires many excellent characteristics such as high reliability, long life, and high air resistance because it plays an important role in controlling signals. In particular, when reliability is required, contact switches must be installed at two or more points, and total control is also required, such as when all switches satisfy the setting conditions or when even one setting condition is satisfied.
