Product details

Silicone Elastomer 4x4 button keypad for 3mm LEDs

• 4x4 grid of 10mm silicone buttons
• Designed for use with the Adafruit Trellis
• These white, blue, red and yellow 3mm LEDs are perfect for this
• Easy to clean

What will this work with?
This silicone keypad is designed for use with Adafruit’s Trellis. It will act as an overlay to the Trellis and safeguard the LEDs, and also work as a functional button by connecting the conductive rings on the Trellis when pressed. You may connect several Trellis’ together in a tile fashion, and in turn lay several of these alongside each other.

The perfect fit and keeping it clean
Each button covers a 10mm by 10mm surface area and is 10mm tall, with a 5mm spacing between each – which upon pressing allows for 3mm of travel. This means you can only use this with 3mm LEDs, 5mm will be too big. These white, blue, red and yellow LEDs are great for use with this Elastomer as they fit the 3mm requirements and are each rated at only 3.5V.

You can easily trim this down if required due to the silicone being so soft, but this will only be required if you’re making a tight enclosure. The silicone is also highly durable and easy to clean by using warm soapy water.

Specifications:
Compatible LEDs 3 mm
Button Size (W x D x H) 10 mm x 10 mm x 10 mm
Button Spacing 5 mm
Button Travel 3 mm

Is this an actual switch with contacts, or does it only help me to build one?
