Device for selecting the color of weft threads in looms, characterized in that the mechanism controlling the weaving programme transmits a mechanical order to a so called color selector which converts the said order in a first electric signal which is sent to a synchronization device and is momentarily stored therein, whereas a second signal is produced by a switching disc and a contactless switch as a function of the rotation of the drive shaft of the loom, whereby the said first signal is sent by the said synchronization device to a so called color giver as soon as the said second signal has reached the said synchronization device.
