Step 1: Designing the Circuit of the Soft Switch
. Masking tapes were used as stencil.
Step 2: Applying the Conductive Paste on the Fabrics
. 3 coats of the conductive paste were applied to make the print more conductive.
Step 3: Heat Setting the Prints
Step 4: Front and Back Fabrics
. Each rectangular print on the first fabric represented a switch that would be connected to a single LED.
Step 5: Hand Tacking the LEDs to the Fabric
Step 6: Using Interfacing
. The interfacing was cut as shown in the picture.
Step 7: The Final Soft Switch
. The top layer and the bottom layer were connected to the positive pole and to the negative pole of the power supply respectively.
Step 8: Testing Each Button
. Applying a light pressure will cause the top layer to touch with the bottom layer which in turn, will complete a circuit and this is demonstrated by lighting the square LED.
Step 9: Soft Switch Ready for Implementation
. This switch can therefore easily be integrated in garments or soft products.
