Please Choose:

This 1 channel dc12v mini rf remote control momentary switch works in momentary mode. Press and hold remote button, switch on electrical device; release button, switch off electrical device. Applications include light remote control, motor remote control, garage door remote control, etc.



  • Wireless control, easy to install.
  • Control Lights, Motors, Fans, electrically operated Doors/ Locks/ Windows/ Blinds/ Cars or other electrical devices with voltage AC 110~240V or DC 0~28V.
  • You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless signal can pass through walls, floors and doors.
  • Reliable control: The transmitter (Encoding) and the receiver (Decoding) use an 8-bit code.
  • One/several transmitters can control one/several receivers simultaneously.
  • If you use two or more receivers in the same place, you can set them with different codes.
  • Transmitting Frequency: 315MHz / 433MHz

  • Channel: 1 CH
  • Control Mode: Momentary (Press and hold -> On; Release -> Off)
  • Coding Type: Fixed code
  • Coding Setting: By soldering
  • Power Supply (Operating Voltage): DC12V±1V (S1SM-DC12), DC6V±1V (S1SM-DC06), DC9V±1V (S1SM-DC09), DC24V±1V (S1SM-DC24)
  • Working Voltage Range of Relay: AC110~240V or DC0~28V
  • PCB Size: 45mm x 28mm x 20mm
  • Maximum Working Current: 1A / each channel


  • Model No.: C-1
  • Channel: 1 CH
  • Remote Control Distance: 100m / 300ft (theoretically)
  • Encode: Fixed code by soldering
  • Unit size: 58mm x 39mm x 16mm
  • Power Supply: 1 x 23A -12V battery (included, can be used for 12 months)


  • Initial state: NO, COM = Normally Open; NC, COM = Normally Closed.
  • 1) Press the button and hold: Turn on relay (connect COM and NO, disconnect COM and NC)
  • 2) Release the button: Turn off relay (disconnect COM and NO, connect COM and NC)


  • The theoretical distance is 100m, which shall be operated in an open ground; no barriers and no any interference. But in actual operation, it is hindered by trees, walls or other obstacles, or interfered by other signals. Therefore, the actual distance can not reach 100m. If you need longer range, please choose other series of remote control, such as CB Serie (1000m/3000ft) - Click here; Or you can add the External Extend Antenna (model:0020909) on the receiver to improve the range - Click here.
