Abstract
A rocker lever assembly includes a housing, an operation device, a switch device, a restoring device, and two sensing variable resistors. The operation device includes a first pivot seat, a second pivot seat, and a control lever. The switch device includes a base, a contact terminal, a contact plate, and a cover plate. The control lever is depressed to cause the under surface of the second pivot seat to depress the cover plate. Thus, the switch device is hidden in the housing, thereby reducing the volume of the rocker lever assembly. In addition, the contact slide is moved on the resistance plate of the casing by guidance of the drive member, thereby greatly enhancing the sensitivity of each of the two sensing variable resistors.
Claims18
A rocker lever assembly, comprising:
- a housing;
- an operation device mounted in the housing and including a first pivot seat pivotally mounted in the housing, a second pivot seat pivotally mounted in the housing and located under the first pivot seat, and a control lever mounted on the first pivot seat and the second pivot seat to pivot the first pivot seat and the second pivot seat;
- and
- a switch device mounted in the housing and including:
- a base mounted in the housing and having an inside formed with a circular recess having a bottom formed with an annular protruding flange;
- a contact terminal embedded in the flange of the base and including two spaced first contact points exposed from the flange of the base and a second contact point located between the first contact points and exposed from the flange of the base;
- a contact plate flexibly mounted in the flange of the base and having a periphery rested on the first contact points of the contact terminal and a central portion spaced from the second contact point of the contact terminal;
- and
- a cover plate mounted on the flange of the base and having a central portion formed with an elastic press piece rested on the central portion of the contact plate to press the central portion of the contact plate to contact the second contact point of the contact terminal;
- wherein the control lever is depressed to cause an under surface of the second pivot seat to depress the cover plate.
