{"title":"Gravity: Digital Wireless Transmit Switch (433MHz)","handle":"gravity-digital-wireless-transmit-switch-433mhz","url":"/products/gravity-digital-wireless-transmit-switch-433mhz","description":"A simple 433 MHz RF wireless switch set that transmits digital signals between a transmitter and receiver module. Based on Gravity interface connectors, it works with any microcontroller that can read and write digital signals — no complex AT commands or pairing protocols required.\n\nThe transmitter supports 15 button states, and the receiver offers multiple working modes including inching, latching, self-locking, and interlocking. The system supports one-to-many and many-to-one configurations with a pairing function on the receiver.\n\nKey Features\n\n\n433 MHz RF Communication – Strong wall penetration, no Wi-Fi or Bluetooth required\n\n15 Button States – Multiple control signals from a single transmitter\n\nPairing Function – Receiver supports one-to-many and many-to-one setups\n\nMultiple Modes – Inching, latching, self-locking, and interlocking\n\nUltra-Low Standby Power – Transmitter standby current less than 10 µA at 5 V\n\nWorking Voltage – 3.3 V to 5.0 V DC\n\nIndoor Range – Approximately 15 metres\n\n\nSpecifications\n\n\nTransmitter Current – 10 mA active, <10 µA standby (at 5 V)\n\nReceiver Current – 6 mA active, 3 mA standby (at 5 V)\n\nFrequency – 433 MHz\n\nInterface – Digital (Gravity connector)\n\nTransmitter Size – 47 × 32 mm\n\nReceiver Size – 37 × 32 mm\n\n\nIdeal For\n\nRemote control projects\nWireless doorbells\nUpgrading wired buttons to wireless\nWireless signal transmission between devices\n\n\nPackage Contents\n\n1× Gravity Digital Wireless Switch (transmitter and receiver)\n1× Gravity Digital Sensor Cable\n\n\n\nNote: 433 MHz is a licence-free frequency band in most regions.
