USB Remote Power Switch,Dc 3.6V 5V 6V 12V 24V 2A Wireless Adapter For Sale

The QIACHIP KR-USB remote receiver adds reliable, long-range wireless control to any low-voltage USB circuit. Plug the unit inline between your power source and load, pair one or more 433 MHz remotes, and select the switching behavior that matches your application—whether that’s turning on LED strips from across the warehouse, cycling aquarium pumps without opening the cabinet, or integrating with a microcontroller project that needs a simple RF link.

Press the raised learning button the required number of times to select the desired mode, then press the selected button on the remote control. The status indicator light will confirm successful pairing. If you need to reconfigure, you can clear the list by pressing the reset function nine times.

QIACHIP KR-USB supports five distinct working modes. Select the mode before pairing.

1. Momentary (Inching)

• Select Mode: Press the [LEARN button] on the receiver 1 time → LED stays solid;
• Pair Remote: Within 5 seconds, press any button on the remote once → LED blinks 3 times and turns off (pairing complete);
• Usage Logic: Press and hold the paired remote button → Receiver output turns ON; Release the button → Output turns OFF (stops working when released).

2. Toggle (Self-lock)

• Select Mode: Press the [LEARN button] on the receiver 2 times → LED stays solid;
• Pair Remote: Within 5 seconds, press any button on the remote once → LED blinks 3 times and turns off (pairing complete);
• Usage Logic: Press the paired remote button once → Receiver output turns ON; Press the same button again → Output turns OFF (toggles state with each press).

3. Latching (Inter-lock)

• Select Mode: Press the [LEARN button] on the receiver 3 times → LED stays solid;
• Pair Remote: Within 5 seconds, first press remote “Button A” (set as ON), then press remote “Button B” (set as OFF) → LED blinks 3 times and turns off (pairing complete);
• Usage Logic: Press remote Button A → Receiver output turns ON; Press remote Button B → Output turns OFF (two buttons control ON/OFF separately).

4. Time-delay OFF

• Select Mode (by delay time):

5-second delay: Press the [LEARN button] on the receiver 4 times → LED stays solid;

10-second delay: Press the [LEARN button] on the receiver 5 times → LED stays solid;

15-second delay: Press the [LEARN button] on the receiver 6 times → LED stays solid;

20-second delay: Press the [LEARN button] on the receiver 7 times → LED stays solid;

• Pair Remote: Within 5 seconds, press any button on the remote once → LED blinks 3 times and turns off (pairing complete);
• Usage Logic: Press the paired remote button once → Receiver output turns ON; After releasing, the output will turn OFF automatically after the set delay time .

5. Power-on Auto-On

• Select Mode: Press the [LEARN button] on the receiver 8 times ;
• Pair Remote: No remote operation;
• Usage Logic: Receiver output turns ON automatically when powered on .

Clear All Pairings (Reset)

• Operation: Press the [LEARN button] on the receiver 9 times continuously → LED blinks 5 times and then turns off;
• Effect: All paired remotes and mode settings are cleared; re-pair or select new modes as needed.

Tip: To change the mode for the same remote control button: First, press the [LEARN button] 9 times to clear all pairings, then select the new mode.
