Frequently Asked Questions
Q: What control modes does this RF wireless relay switch support?
A: This relay switch kit supports three control modes: Self-Lock (toggle on/off with the same button), Inter-Lock (one button turns it on, another turns it off), and Jog/Momentary (the relay is active only while the button is held down). You can select the mode that best matches your DIY project needs.
Q: Does the remote control battery come included?
A: No — the CR2016 button battery for the remote transmitter is not included in the package. You will need to purchase one separately before using the remote control.
Q: What is the maximum wireless range of this relay module?
A: The 315 MHz RF signal can reach up to 50 metres (approximately 164 feet) in open space without obstacles. Range may be reduced in environments with thick walls or significant interference, though the signal is designed to penetrate common building materials such as standard interior walls, floors, and doors.
Q: What devices or applications can this wireless relay switch be used with?
A: This kit is well-suited for a wide range of DIY and automation applications, including garage door openers, lighting circuits, alarm systems, machine tool controls, home automation projects, elevator controllers, and general household appliance switching — any device operating on or controllable through a DC 12V relay circuit.
