An electrical switch including at least one switching unit includes: a contact lever and two parallel plates, between which the contact lever is resiliently retained by way of pins. The contact lever is inserted into an electrically non-conductive housing of the switching unit, wherein at least one of the pins forms a retaining pin, wherein the length of the retaining pin exceeds the distance between the parallel plates and wherein the retaining pin extends through a hole in each of the two plates and is retained by one pin end in a retaining recess in the housing and by the other pin end in an opposite retaining recess in the housing.
