Single & Double Switch Modules – ESM / DSM The single switch module ESM and the double switch module DSM are ready-to-install units, consisting of: • • • • Switches: K12 (for both ESM or DSM) K12G (DSM only with two switching-points) PVA1H4 (ESM only) PC board Rubber cap Optional cable or connector The rubber cap offers the possibility to use both switch modules under severe ambient conditions where dust, water, oil, solvents etc. can effect or destroy the function of standard switches. With the rubber cap the two modules are sealed to IP 65 when mounted.
