Key Pad Instrument membrane switch prototype With 1.25MM Pitch
Female Connector
Components
- Overlay: The top layer, usually printed with graphics and text. It is made
of a durable material like polyester or polycarbonate.
- Spacer Layer: This layer separates the upper and lower circuits, allowing the
switch to function without constant contact.
- Circuit Layer: Conductive traces are printed on this layer, usually made of
silver or carbon, which complete the circuit when a button is
pressed.
- Adhesive Layer: Used to attach the membrane switch to the device.
Steps to Create a Prototype
- Design: Create a design for the switch, including button shapes, sizes,
and graphics.
- Material Selection: Choose appropriate materials for the overlay, spacer, and circuit
layers.
- Circuit Design: Design the circuit layout using software tools.
- Printing: Use screen printing or digital printing to produce the overlay
and circuit layers.
- Assembly: Layer the components together and apply adhesive.
- Testing: Test the prototype for functionality, durability, and user
experience.
