RTTXA08 Transmitter OR 1 PC RTRXB08 Receiver

(It is recommended to buy both transmitter and receiver) Please contact me for detailed instructions.

Description:

This is a wireless remote control switch with feedback functionality—no configuration is required. As long as the

transceiver’s “Frequency and ID” settings are matched, the device can be controlled. The built-in LED indicator

on the transmitter provides visual feedback on the receiver’s switch status.
