A relay is an electro-magnetic switch which is useful if you want to use a low voltage circuit to switch on and off a light bulb (or anything else) connected to the 220v mains supply.
Re: How to safely use 220V relays? #2. Apr 16, 2012, 06:02 pm. The basic rule is keep high voltage wiring away from low voltage wiring - on a PCB that means a copper-clear zone of 10mm or so. All high voltage side wiring must be insulated (this means solder-resist on a PCB), no bare copper visible.

SRD-S-112DM sanyou relay Hf3ff relay SRD-24VDC-SL-C 5v 220v mini T73 electronic relay switch 12v. Sealed. ... 40A RELAY 5PIN 5P car automotive relay socket wire harness.
SSR-GJ series for small high-power solid-state relays, input control voltage is 3~5V DC, output adopts a unidirectional thyristor reverse parallel, dv/dt resistant ability is high, the output load voltage range of 5~220V DC. Great to meet customers various requirements in different places.
The Pump Start Relays have been created to provide that reliability – as well as a lockable NEMA rated enclosure – at an economical price. Available in a choice of three models to accommodate a variety of power sources and landscape needs, the product is fully compatible with all standard 24VAC controllers.
