Grässlin time switch modules are largely protected against
„spike“ or interference voltages. If faults still occur, counter-
measures against foltage peaks can be taken with familiar
elements (varistors, suppressor diodes etc.). Particular
attention must be paid to this when inductive loads are
connected.
