Customizable Surface Mount Backlit Light Switch For Hairfoil Device

Example Features

• Indicator Light: A separate LED to indicate when the device is powered on.
• Color Changing: Allow users to select different backlight colors based on their preference or mood.
• Dimmer Functionality: Include a dimming option for the backlight for added control.

Prototyping and Testing

• User Testing: Conduct usability testing to ensure the switch meets user needs and is easy to operate.
• 3D Printing: Consider prototyping the switch housing using 3D printing for rapid iteration.

Design Considerations

1. User Interface:

   • Tactile Feedback: Ensure the switch provides a tactile response to indicate when it has been activated.
   • Size and Placement: Design the switch to be easily accessible and operable, considering the ergonomics of the user.

2. Functionality:

   • On/Off Control: Ensure the switch can easily control the light function of the device.
   • Backlighting: Consider using LED lights for backlighting, which can enhance visibility in low-light conditions.

3. Customization:

   • Personalized Graphics: Allow for custom graphics or labels that can be applied to the switch surface.
   • Color Options: Offer different colors for the backlighting to match user preferences or device aesthetics.

Components

1. Control Circuit:

   • Microcontroller: Use a small microcontroller to manage the switch state and control the backlighting.
   • Power Supply: Ensure compatibility with the hair foil device's power requirements.

2. Switch Mechanism:

   • Metal Dome Switch: For tactile feedback and durability.
   • Membrane Switch: For a low-profile option if space is a concern.

3. Housing:

   • Surface Mount Enclosure: Design a robust housing that can be easily attached to the hair foil device.
   • Water Resistance: Consider sealing options to protect against moisture and heat.

4. Backlighting:

   • LEDs: Incorporate surface-mounted LEDs for efficient lighting.
   • Diffuser: Use a diffuser to soften and even out the light from the LEDs.

Specification:

1)Material (for front or face overlay)

Polyester:

1.Highly versatile for embossing

2.Highly resistant to chemicals

3.Better durability

4.For internal and external use, UV resistance

Polycarbonate:

1.Different surface(Glossy, Matt) and thickness(From 0.12mm~2mm)

2. cost-effective in price

3.For internal and external use

2) Embossing

Rim embossing/pillow embossing/dimple embossing

Graphic overlays can be embossed in order to insert domes/LED, leave space for mechanical keys/LED and provide tactile indications and better tactile feeling.

3)Windows(for display function)

1. print different colors windows, As transparent grey/Red/green window for display

2. Clear/Transparent window for LCD display

2. Matt/semi-transparent window for LED

4)Keys/buttons

Tactile keys---with metal dome or poly dome

Non-tactile--silver printing dots with flat key

5) Embeded LEDs

Small, brilliant lights only about 0.02’’ in height. Avaliable in several vibrant colors.

LED colors: white, yellow, orange, green, red, or double colors LED.

6)Cable

It is an extension of the printed circuit and is used to communicate with your device.

7)Types of connector

1.Zero insertion force (ZIF) connector; 2.Female connector; 3.male connector

8) EMI / RFI / ESD Shielding

use an aluminum foil shielding / a clear ITO electrical conductive polyester

9)Adhesive

mostly used are 3M-double-side glue

10)Backplate-

in aluminum, polycarbonate, acrylic, PCB
