Snap-Action Switching Element With Opener or Closer Contact

A snap-action switching element with normally closed or normally open contact comprises:

• a housing,
• a first contact point fixed to the housing,
• a second contact point fixed to the housing,
• a contact arm having a rest position and a switching position having a first contact arm end and a second contact arm end,
• an actuating member guided in the housing,
• a rocker switch having a rocker switch axis of rotation extending transversely to the longitudinal axis of the housing and having a first free end and a second free end,
• a tension spring,
• wherein the actuating member is configured to move the contact arm between the rest position and the switching position,
• wherein the rocker switch can be rotated at the first free end about the rocker switch axis of rotation,
• wherein the tension spring is hooked onto a spring hook-in section at the second free end of the rocker switch;
• wherein the actuating member is guided perpendicularly to the longitudinal axis of the housing and is in engagement with the rocker switch between the first free end and the second free end of the rocker switch,
• wherein the second contact point provides a contact arm axis of rotation parallel to the rocker switch axis of rotation, against which the first contact arm end is pressed by the tension spring suspended in the contact arm,
• wherein the second contact arm end of the contact arm contacting the first contact point in the rest position in the case of a normally closed contact or, in the case of a normally open contact, contacting the first contact point in a normally closed position, is arranged at a distance from the first contact point in the case of a normally open contact,
• wherein the actuating member has a rocker bearing opening which is provided transversely to its direction of movement and into which rocker bearing opening engages a rocker bearing actuating section provided transversely to a main plane of the switching rocker.
