According to a first preferred embodiment at least one plastic element extends at least on a first side of the fixed contacts, which plastic element leaves clear a part of the surface on the first side of the fixed contacts. Sufficient fixation is herein obtained by the plastic element, while it will be apparent that a contact face of the contacts must remain free in order to be able to function as a contact.
