Overview

Touch button switch.jpg

Electronic brick of touch button switch is finger-sized, which can be connected to I/O port of main board or externally disconnected to check the switch state so as to control ON/OFF of LED lamp.

Features

1. Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market. IM120710023_2.jpg

2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock. IM120710023_3.jpg
