Hi Maybe a dry reed relay will fit the bill here. They are designed to handle small signal currents, microamps, up to the ampere region, depending on contact material and size. Because the contacts operate in an inert gas atmosphere, there is minimal surface oxide to breakdown during the switching process.They are preferable to mercury wetted reed relays provided you don't need the extremely high break switching characteristics and power handling of a mercury relay. Dry reed switches did good service in the telephone systems after the old strowgers and crosspoint switches and before solid state switching became the standard.
