The invention relates to an electrical switch (10), particularly of microswitch design, comprising at least one pair of switching contacts (42, 60), which can be moved, relative to one another, between an in-contact position and an out-of-contact position, for the purpose of making and breaking an electrical path leading via the two switching contacts (42, 60), and comprising spring means (40), which bias at least one of the two switching contacts in the direction of one of the two relative positions, the spring means (40) comprising, according to a preferred design, a helical spring (40), which is made of an electrically conductive material, is loaded substantially in the direction of its spring axis, and is located in the electrical path in series with the switching contact pair (42, 60).
