A dry contact (also known as a volt-free contact or potential-free contact) is defined as a contact in which power/voltage is not directly provided from the switch but is instead always being supplied by another source. Dry contacts are known as passive contacts, as no energy is applied to the contacts themselves.A dry contact operates just like an ordinary single-pole ON/OFF switch: when closed, it completes the circuit and allows current to flow; when open, it breaks the circuit and stops current flow. It acts as a secondary set of contacts in a relay circuit, never making or breaking the...
