Abstract

The problem with push buttons or a rocker button for multi-directional controlling is that they either take up a larger amount of area, or for a given limited area that the buttons would have to be made smaller and thus cause ergonomic problems such as inadvertent actu- ation of the wrong button or diiculty in operating the button.

FOUR-WAY MULTI-DIRECTIONAL SLIDE SWITCH

by Robert D. Lloyd

  The problem with push buttons or a rocker button for multi-directional controlling is that they either take up a larger amount of area, or for a given limited area that the buttons would have to be made smaller and thus cause ergonomic problems such as inadvertent actu- ation of the wrong button or diiculty in operating the button.

  The advantage of the 4-way Slide Controller is that for the same given limited space as the push or rocker switch (above) that the control button can be made much larger and thus provide greater ergonomic benefits in reducing inadvertent actuation of the wrong button or diiculty in operating the button.

  The 4-Way Slide Controller can take several embod- iments. However, the basic design consists of a single button that can be SLID in any one of 4 ditferent direc- tions to cause different electrical connections to be made to provide user input to the product. The button has a gasket that: 1) provides sealiig ofthe switch button, and

2) provides a means of force to return the button to its center neutral position. The gasket is retained within an interior-walled-pocket of the product's housing that has studs at its base that mate with holes in the PCB to insure initial alignment between the switch and PCB and to prevent inadvertent switch actuation from PCB shit&g ifthe product is dropped or twisted. In order to prevent or reduce erroneous switch actuation (common with

the closely packed push or rocker controls), the button can only be slid in one direction at a time due to the keyed design of the opening in the product's housing. In the lead frame embodiment #l, this feature can also be redundantly stamped into the lead frame. This design (in both the housing and lead frame) also serves the...
