Abstract

The switch and cable unit shown in the figures utilizes a flexible printed circuit card to replace the switch, mounting, connecting and conductor functions of the prior art. The essential element of the switch and cable unit is a one-piece card which replaces the previous multiple-part designs. Figs. 1 and 2 show respective side and top views of the unfolded switch and cable, and Fig. 3 shows how the button and base are assembled in the folded view. A flexible printed card 10 having printed wiring 12 etched into it is attached to a card stiffener 14 and switch button 16. Button 16 includes four springs 18 on the four corners aligned to rest on the area of stiffener 14 outside of the flexible printed circuit when the pin 20 is inserted through the hole 22.

Composite Switch and Cable

The switch and cable unit shown in the figures utilizes a flexible printed circuit card to replace the switch, mounting, connecting and conductor functions of the prior art. The essential element of the switch and cable unit is a one-piece card which replaces the previous multiple-part designs. Figs. 1 and 2 show respective side and top views of the unfolded switch and cable, and Fig. 3 shows how the button and base are assembled in the folded view. A flexible printed card 10 having printed wiring 12 etched into it is attached to a card stiffener 14 and switch button 16. Button 16 includes four springs 18 on the four corners aligned to rest on the area of stiffener 14 outside of the flexible printed circuit when the pin 20 is inserted through the hole 22. When the button is depressed, contact ribs 24 below the printed circuit card on the button force the two printed wire portions together when in the folded view, as shown in Fig. 3, making contact.
