Relays

Relays are essential components in many applications, primarily serving as switches to control high-voltage devices and systems. They allow low-voltage circuits to safely manage and activate high-voltage components, offering versatility and safety. Most relays feature a common contact point that connects to a neutral position, ensuring stable and reliable operation. Available in a wide range of voltage ratings, these devices also include wireless options for enhanced flexibility. Wireless relays are ideal for environments where traditional wiring isn’t feasible or where existing wiring has been compromised.
