The switch of Relay is a resistor that varies between specified values of a controlling input voltage.

The switch is not quite ideal, in that the resistance can not change from 0 to infinity, but must always have a finite positive value. By proper selection of the RESON and RESOFF resistances, they can be effectively zero and infinity in comparison to other circuit elements.
