This tiny module allows LEDs and other items to turn on automatically when it senses dark. The module consists of a CR2032 coin cell battery holder, several small components and an on-off slide switch on one side of the module, the reverse side of the PCB has a tiny light sensor - board has been designed so the sensor can peek through a small hole in your fabric or project while the rest of the module can remain concealed behind it. The onboard battery can also power your attached LEDs.

The module will automatically turn off in daylight and back on again in the dark. No soldering is required - the contacts on the PCB have been specially designed to make contact with our conductive thread.
Dimensions: 44mm L x 20mm W x 4.5mm H.
This push button switch is a must-have item for anyone working with wearables, e-textiles, or e-fashion electronics.
