Abstract

Melde- und/oder Schutzeinrichtung für Prozeßgrößen, die über eine von der Prozeßgröße abhängige Verstellung eines Erfassungsgliedes (4) ein Auslösesystem (2) anregt, das über ein Koppelglied (5) zu einer sprungartigen Betätigung eines beweglichen Kontaktelementes (6) eines Hilfsschalters (7), bestehend aus einem festen (8) und beweglichen (6) Kontaktelement, führt. Das bewegliche Kontaktelement (6) wird mittels eines federnden, aus elektrisch leitfähigen Material bestehenden Kontaktarmes (9) gehalten, der sich an einem Trägerteil (11) im Gehäuse der Schutzeinrichtung befindet.Signaling and / or protective device for process variables that over an adjustment of a detection element depending on the process variable (4) stimulates a trigger system (2), which has a Coupling member (5) for a sudden operation of a movable Contact element (6) of an auxiliary switch (7), consisting a fixed (8) and movable (6) contact element, leads. The movable contact element (6) is by means of a resilient, made of electrically conductive material Contact arm (9) held on a support member (11) is located in the protective device housing.

Um ein bestimmtes Schaltvermögen des Hilfsschalters (7) zu gewährleisten, ist eine Mindestkontaktkraft erforderlich. Andererseits darf eine maximale Kontaktkraft nicht überschritten werden.To a certain switching capacity of the auxiliary switch (7) ensure a minimum contact force is required. On the other hand must not exceed a maximum contact force will.

Diese Vorgabe wird dadurch eingehalten, daß der Kontaktarm (9) in einem Führungsschlitz (10) des Trägerteils (11) in Bezug auf das feste Kontaktelement (8) des Hilfsschalters (7) derart angeordnet und ausgebildet ist, daß bei geschlossener Kontaktstrecke des Hilfsschalters (7) das bewegliche (6) und feste (8) Kontaktelement mit einer vorgegebenen Kontaktkraft aneinanderliegen.

Figure 00000001
This requirement is met in that the contact arm (9) is arranged and designed in a guide slot (10) of the carrier part (11) with respect to the fixed contact element (8) of the auxiliary switch (7) such that when the contact path of the auxiliary switch ( 7) the movable (6) and fixed (8) contact element lie against one another with a predetermined contact force.
