Abstract

Temperaturabhängiger Schalter (10), der einen ersten und einen zweiten stationären Kontakt (48, 50) sowie zumindest ein temperaturabhängiges Schaltwerk (14) mit einem beweglichen Kontaktglied (40) aufweist, wobei das zumindest eine Schaltwerk (14) in seiner ersten Schaltstellung das Kontaktglied (40) gegen den ersten Kontakt (48) drückt und dabei über das Kontaktglied (40) eine elektrisch leitende Verbindung zwischen den beiden Kontakten (48, 50) herstellt und in seiner zweiten Schaltstellung das Kontaktglied (40) zu dem ersten Kontakt (48) beabstandet hält. Das zumindest eine temperaturabhängige Schaltwerk (14) weist ein erstes temperaturabhängiges Schnappteil (30) auf, das bei Überschreiten einer ersten Schalttemperatur aus seiner geometrischen Tieftemperaturkonfiguration in seine geometrische Hochtemperaturkonfiguration umschnappt und bei einem anschließenden Unterschreiten einer ersten Rückschalttemperatur wieder aus seiner geometrischen Hochtemperaturkonfiguration zurück in seine geometrische Tieftemperaturkonfiguration umschnappt. Der Schalter (10) weist ferner ein zweites temperaturabhängiges Schnappteil (44) auf, das bei Überschreiten einer zweiten Schalttemperatur aus seiner geometrischen Tieftemperaturkonfiguration in seine geometrische Hochtemperaturkonfiguration umschnappt und bei einem anschließenden Unterschreiten einer zweiten Rückschalttemperatur wieder aus seiner geometrischen Hochtemperaturkonfiguration zurück in seine geometrische Tieftemperaturkonfiguration umschnappt. Ein Umschnappen des ersten Schnappteils (30) aus seiner geometrischen Tieftemperaturkonfiguration in seine geometrische Hochtemperaturkonfiguration und/oder ein Umschnappen des zweiten Schnappteils (44) aus seiner geometrischen Tieftemperaturkonfiguration in seine geometrische Hochtemperaturkonfiguration bringt das zumindest eine Schaltwerk (14) aus seiner ersten Schaltstellung in seine zweite Schaltstellung. Die zweite Rückschalttemperatur ist niedriger als die erste Rückschalttemperatur und das zweite Schnappteil (44) ist dazu eingerichtet, das Kontaktglied (40) auch dann zu dem ersten Kontakt (48) beabstandet zu halten, wenn sich der Schalter (10) über die erste und die zweite Schalttemperatur erhitzt und nachträglich auf eine Temperatur zwischen der ersten und der zweiten Rückschalttemperatur abgekühlt hat.Temperature-dependent switch (10) having a first and a second stationary contact (48, 50) and at least one temperature-dependent switching mechanism (14) with a movable contact element (40), wherein the at least one switching mechanism (14) in its first switching position presses the contact element (40) against the first contact (48) and in the process establishes an electrically conductive connection between the two contacts (48, 50) via the contact element (40) and in its second switching position keeps the contact element (40) at a distance from the first contact (48). The at least one temperature-dependent switching mechanism (14) has a first temperature-dependent snap part (30) which, when a first switching temperature is exceeded, snaps from its geometric low-temperature configuration into its geometric high-temperature configuration and, when a first switch-back temperature is subsequently undershot, snaps back from its geometric high-temperature configuration into its geometric low-temperature configuration. The switch (10) further comprises a second temperature-dependent snap part (44) which snaps from its geometric low-temperature configuration into its geometric high-temperature configuration when a second switching temperature is exceeded and snaps from its geometric high-temperature configuration back into its geometric low-temperature configuration when a second switch-back temperature is subsequently undershot. Snapping the first snap part (30) from its geometric low-temperature configuration into its geometric high-temperature configuration and/or snapping the second snap part (44) from its geometric low-temperature configuration into its geometric high-temperature configuration brings the at least one switching mechanism (14) from its first switching position into its second switching position. The second switch-back temperature is lower than the first switch-back temperature and the second snap part (44) is designed to keep the contact member (40) at a distance from the first contact (48) even when the switch (10) has heated up above the first and second switching temperatures and subsequently cooled down to a temperature between the first and second switch-back temperatures.
