Embodiment Construction

[0024] exist figure 1 and 2 The electrical snap-action switch 1 shown in FIG. 2 comprises a switching lever 2 which is arranged centrally in a housing 3 and is supported axially displaceably in two regions of the housing 3 . In this case, the upper and lower stop areas 4 and 5 on the switching lever 2 determine the movement path of the switching lever 2 . exist figure 1 In the rest position shown in , the switching lever 2 is held by the spring force of the spring element 6 into the upper position in which the upper stop region 4 rests against the housing 3 .

[0025] Approximately in the center of the switch lever 2, two opposite notches are mounted on the switch lever 2, wherein each of these notches is used to accommodate the ends of two snap-in springs 7 arranged on both sides of the switch lever 2. one of the department. The two snap-in springs 7 are designed as two approximately omega-shaped spring arms and are arranged approximately symmetrically to the direction of...

Abstract

The invention relates to an electrical snap-action switch with a contact link which can be actuated via a switching plunger and a bistable spring and which is connectable in a first switching position to at least one first contact pair and in a second switching position to at least one second contact pair, wherein the spring arrangement on both sides of the switching plunger has at least one spring arm, via which, in addition, the contact link is movable transversely with respect to the movement direction of the switching plunger up to a movement end position in the event of breakage of one of the spring arms, wherein a sliding ramp is provided in the movement path of the contact link, which sliding ramp spaces apart at least one contact of the contact link in the movement end position from the associated contact of the respective contact pair in the event of breakage of one spring arm.

Description

technical field [0001] The invention relates to an electrical snap-action switch (Schnappschalter) with a contact bridge actuatable via a switch lever and a bistable spring assembly, which can be connected in a first switching position to at least one first contact pair ( Kontaktpaar) in the second switching position with at least one second contact pair, wherein the spring assembly has at least one spring arm respectively on both sides of the switch lever, in addition to this, the contact bridge can be broken when one of the spring arms breaks Travel transversely to the direction of movement of the switching lever to the final travel position (Verschiebeendlage). Background technique [0002] A large number of electrical snap-action switches are known from the prior art, in which pairs of contacts separated from one another can be connected to one another via contact bridges in each of two switching positions. In this case, the position of the contact bridge is influenced ...
