Coherent stepped searcher-commutator for low-voltage signals

Conclusion

Use of the coherent effect is a highly effective means of increasing the stability of junction contact resistance of stepped searchers when commutating signals U_C > U_F and U_C≪ U_F; a coherent stepped searcher can be successfully used for commutation of microvolt signals in electronic measuring circuits [4].

It should be noted that the coherent effect as a means of increasing the conductivity of contacts (for example, in multipoint switches widely used as well in other (other than searchers) commutating devices having brass-bronze contacts (for example, in multipoint switches widely used in low-voltage measurement circuits). Electromagnetic irradiation in this case replaces the traditional mechanical cleaning of tarnish films from the contacts.
