This is a safe widely used and flexible remote relay. Receiver parameters : Model number: NO1J frequency: 433MhzWorking Voltage: DC3.5V-DC12V Wide Range Working Voltage DC3.7V 4.5V 5V 6V 9V 12V Max Load: 1A (have better Load less than 700ma) Quiescent Current: 5ma Relay Working Current: 30ma Size: 25*11*8mm Working Mode: Momentary. Toggle .Latched ,Delay time 10S adjustable.you can change working model by yourself. (Notice: we send Momentary mode default . Encoding Type: Learning point to add extra transmitter Normally Open Port (NO) Common Port (COM) Normally Close Port (NC) Input DC3.5V-DC12V Output 0V Switching Value Momentary---Press and hold relay On; Release relay Off.(one channel switch need one button remote) Toggle----Press relay On; Press same button again relay Off .(one channel switch need one button remote) Latched----Press relay On; Press other button relay Off . ( one channel switch need 2 buttons remote ) Delay time : Press remote control button, the corresponding relay actuates and keeps working until the time out. We've paired it up, so just wire it up and use it when you get it. Clearing Code: Connect the Learning Dot and hold on . Until the receiver Led indicator flash for 6 times, it mean Clearing code successfully Remote control parameters: frequency: 433Mhz Working current: ≤12mA Working Voltage：3.7v -- 9v Transmission Distance: 10-50 Meters Package Include: 1 x Receiver(without cover) 1x Transmitter Review: Works great on 3VDC. - I was a little worried about whether or not these circuits would work on 3VDC since the title states "3.7 to 12VDC". Connected them to 3VDC (2 AA batteries) and it works flawlessly. I don't need to mess with the different available modes, so I don't know if they work or how hard it is to implement, but the momentary function works perfectly for me. Review: Reached 500 feet range outdoors line of sight - Simple on/off wireless switch mechanism. Ours came pre-paired. Reached 500 feet line of sight in town. Uses about 20-50 mA during transmissions on 5V, average around 15 mA. Receiver has both Normally Open and Normally Closed contacts. After losing signal, appears to turn off after around 10 seconds. ## Features - it is a small size and easy installation. high sensitivity, with flexible control ，five working model for choose,It adopts non-directional wireless encoding technology, allowing independent control without mutual interference. - easy to use : We have made transmitter and receiver working together and test it before ship it,when you get it don't need to do anything ,just install it. - the RF remote control adopts RF technology, stable signal. Signal of the wireless RF switch can pass through walls, floors and doors, steadily control receiver from any place within a reliable distance, Max range is up to 50 meters with no obstacle. - it is mainly used in swtich, lamps, relays, remote controller, circuit boards,trumpet, power switch,home wireless control and security industry and battery powered on/off for small devices, etc. and other fields. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08F7FFQ14 | | Best Sellers Rank | #141,290 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #577 in Garage Door Keypads & Remotes | | Brand Name | ZABLL | | Circuit Type | 3-way | | Compatible Devices | Various Wireless Controlled Devices | | Compatible with Vehicle Type | Passenger Car, Van, RV | | Connectivity Protocol | RF | | Connector Type | Screw Terminals | | Contact Material | Copper | | Contact Type | Normally Open | | Control Method | Remote | | Control Type | remote | | Controller Type | Push Button | | Current Rating | 1 Amps | | Customer Reviews | 3.9 3.9 out of 5 stars (67) | | Item Dimensions | 0.98 x 4.33 x 0.43 inches | | Item Weight | 9.07 g | | Manufacturer | ZABLL | | Material Type | Copper | | Model | NO1J | | Mounting Type | PCB Mount | | Number of Positions | 1 | | Operation Mode | Momentary, Toggle, Latched | | Specification Met | CE | | Switch Type | Push Button | | Terminal | Through Hole | | UPC | 732489635991 | | Wattage | 12 watts | ## Product Details - **Brand:** ZABLL - **Circuit Type:** 3-way - **Connector Type:** Screw Terminals - **Contact Type:** Normally Open - **Current Rating:** 1 Amps - **Item dimensions L x W x H:** 0.98 x 4.33 x 0.43 inches - **Material:** Copper - **Operation Mode:** Momentary, Toggle, Latched - **Switch Type:** Push Button - **Terminal:** Through Hole ## Images ![3.7-12V Wireless Remote Control Switch Mini Small PCB 433mhz RF Transmitter,3V -12V Battery Power Circuit Micro Controller for DIY - Image 1](https://m.media-amazon.com/images/I/51JboU7Ok2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great on 3VDC. *by G***P on April 29, 2025* I was a little worried about whether or not these circuits would work on 3VDC since the title states "3.7 to 12VDC".
