The Pololu RC Switch with Relay (Assembled) is an electronic component designed for the control of electrically isolated loads in radio control (RC) systems, offering a reliable, versatile, and safe solution for automation, modelling, and robotics projects. With its configurable activation threshold and adjustable switching direction, this device enables precise control tailored to each application.
It features an advanced safe-start function that minimises the risk of unintended activation, providing enhanced protection for your system. This version is supplied fully assembled with a 5V relay, terminal block, and straight male header pins, allowing for easy integration into any hobby RC system without the need for additional soldering.
The included Omron G5LE-14-DC5 power relay is rated to handle up to 10 A under most conditions, ensuring stable and durable performance even in demanding environments.
This SPDT (single pole double throw) relay features a control circuit that interprets incoming radio signals from the RC system, making it easy to control high-power loads such as LED lighting, electric motors, pumps, or irrigation valves. The RC switch measures the width of incoming PWM pulses and compares them to a configurable threshold (±64 µs hysteresis) to determine relay activation.
By default, the threshold is approximately 1700 μs, with the relay activating when the pulse width exceeds this value. Thanks to its learning mode, it is possible to adjust both the threshold and the activation direction to suit different setups.
For optimal performance, it is recommended to power the switch with a 4- or 5-cell NiMH or NiCD battery pack. This pack is typically connected to an RC receiver or servo controller, which then supplies power to the relay.
In summary, the Pololu RC Switch with Relay (Assembled) is the ideal choice for those seeking a reliable and secure remote-control switch for home automation, radio-controlled modelling, or small-scale industrial systems.
The Pololu RC Switch with Relay (Assembled) is designed for the easy control of electrically isolated loads in radio control (RC) systems. Its configurable activation threshold and adjustable switching direction allow flexible integration, while the safe-start feature helps to prevent unintended activations.
This version is fully factory-assembled with a 5V relay, terminal block and straight male header pins soldered, making it easy to integrate into RC systems without additional soldering. The included Omron G5LE-14-DC5 power relay can handle up to 10 A under most operating conditions, ensuring reliable and stable performance.
