Pololu RC Switches With Isolated Solid State Relay Switch

These solid‑state relay modules provide a radio‑control interface that lets a receiver switch a load without any direct electrical connection to the control line. The isolated design protects low‑voltage circuitry while handling bidirectional currents up to several amps at voltages ranging from a few tens of volts. Fast, contact‑less switching eliminates wear and offers reliable operation in remote‑controlled vehicles, UAVs, and other automation projects where space and weight are at a premium.

Integration is straightforward: the modules accept typical RC PWM signals, require only a modest supply voltage, and can be fitted with either soldered leads or plug‑in connectors. Their low on‑resistance and predictable response make them suitable for driving motors, lights, or actuators that need clean, repeatable control without the noise of mechanical relays.
