1. the contact element of a liquid level detection device comprises:

  • By the contact support spring that conductive material is made, this contact support spring is fixed in retainer in the mode of cantilever, and with at the variation of liquid level and rotate, this contact support spring comprises;

    Cantilevered spring arm, this cantilevered spring arm have free end and are fixed in the cardinal extremity of described retainer;

    AndThe contact support portion, this contact support portion is arranged on the free end of described cantilevered spring arm, and wherein primary importance is set in a distolateral place of this contact support portion, and the second place is set in another distolateral place of this contact support portion, the described second place is positioned at the cardinal extremity than the more close described cantilevered spring arm of described primary importance;

    First contact, this first contact is connected in described contact support portion in described primary importance, with the deflection displacement of free end by described cantilevered spring arm and contact support portion with framework on first slide rheostat produce press contacts;

    AndSecond contact, this second contact is connected in described contact support portion in the described second place, with the deflection displacement of free end by described cantilevered spring arm and contact support portion with described framework on second slide rheostat produce press contacts, whereinThe joint place in the centre position between the described primary importance and the described second place, described contact support portion engages integratedly with described cantilevered spring arm, and described bonding station is set so that deflection displacement owing to the free end of described cantilevered spring arm and described contact support portion is applied to described first contact on the described contact support portion and the compressive load of described second contact is in the preset range.
