Abstract

Bei einem Miniaturrelais-Schalter, insbesondere einem MEMS-Schalter, ist zum Schutz gegen Hot Switching ein Schutzwiderstand (W) vorgesehen, der durch einen zusätzlichen Schalter (B) bis zum erfolgten Gleichspannungs-Potentialausgleich an den Kontakten des Schalters (A) in Reihe oder parallel zum Schalter (A) schaltbar ist.
