Abstract

A plug for masking switching contacts, for instance in terminal strips of telecommunication devices, comprising an upper pulling head, a widened central supporting portion, and two lower spring tongues with a guiding web disposed therebetween. The plug is integrally formed and has the function of masking or, respectively, separating solderless, screwless and stripless switching contacts (so-called LSA-PLUS contacts) in terminal strips, wherein the contact points of these switching contacts are not touched by any parts of the plug so as to avoid contamination.
