Schematic diagram of an Interposing relay?

An interposing relay is an electromechanical device used to interface between two circuits, typically for the purpose of signal amplification or isolation. In a schematic diagram, it typically shows a coil connected to a control circuit and one or more sets of contacts connected to the load circuit. When the coil is energized, it creates a magnetic field that closes the contacts, allowing current to flow in the load circuit. This setup helps protect sensitive components from high voltages or currents present in the control circuit.
