Buying Guide

Match relay type to your circuit

Choose the correct contact arrangement (NO/NC, 1NO/1NC, SPDT, DPDT) and voltage rating—e.g., DC24V modules for low-voltage control versus AC-capable relays for mains switching

Check current and voltage ratings

Verify the relay's amperage and voltage ratings exceed your load requirements to prevent contact failure; miniature relays often list max current like 6A for DC loads

Consider metering and diagnostics

Built-in power metering helps monitor consumption and detect faults remotely, useful in automation and energy-conscious installations

Prefer network and integration features

Wi‑Fi, Bluetooth gateways, and Home Assistant compatibility enable remote control, automation and status reporting without needing a separate hub

Evaluate safety and certification

Look for UL or equivalent safety listings and clear wiring documentation to ensure compliant installation and reduce electrical hazards
