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