Problems solved by technology

However, since the rocker switch operates by translating the rocker member about its pivot axis, whereas the button is generally a linear motion device movable along a longitudinal axis substantially perpendicular to the pivot axis of the rocker member, there is a need to maintain a compact design. Also having an interface means or mechanism between the button and the rocker switch is a challenge

Embodiment Construction

[0053] FIG. 1 shows a typical rocker switch 100 . The rocker switch includes a rocker member 110 and a switch mechanism. The rocker member is constructed and arranged to actuate the movable electrical contact of the switch mechanism to at least a first and a second operative position whereby first and second selectable connections can be made. Of course, a rocker switch may have more than two modes of operation. The rocker member 110 is pivotally mounted about a rocker axis 130 and is biased by an internal spring such that once the rocker member moves to a critical threshold position, the internal spring bias moves the rocker member to the next mode of operation Without additional external force. After the rocker member has been moved into an operating mode, it will remain in that operating mode until its operating mode is further switched.

[0054] Figure 1A shows a typical actuation force-displacement diagram for a conventional rocker switch. As shown, the maximum actuat...

Abstract

The present invention relates to a push-button type electrical switch. The electrical switch comprising a push-button, a rocker switching mechanism having a rocker member, resilient urging means, and drive conversion means for converting motion of the push button into motion suitable for changing the operation modes of the rocker switching mechanism, the resilient urging means provides a resilient resistive force against motion of the push button towards the rocker member and for providing an additional resilient resistive force to reduce the apparent differential actuation force required to overcome inertia of the rocker member.

Description

technical field [0001] This invention relates to electrical switches, and more particularly, to push button operated electrical switches. More specifically, the present invention relates to push button switches including rocker switch mechanisms. Background technique [0002] Electrical switches are essential, if not essential, in electrical applications such as electrical appliances, equipment and devices. Of the various types of known switches, perhaps the most widely used are push button switches and rocker switches. Rocker switches typically include a rocker member that can be toggled between at least two selectable stable operating positions corresponding to different selectable modes of operation. A pushbutton switch typically includes a linearly actuated button that is operated by a sequence of simple linear movements, such as by pressing and then releasing the button. [0003] Push button actuated switches including rocker type switch mechanisms are known. Howeve...
