Relais is a compact electromechanical switch that allows you to control a load from a separate control signal. It provides electrical isolation between the control circuit and the load, letting a low power controller operate higher power devices safely. Key benefits - Safe isolation between control and load circuits - Enables control of higher power devices from a low power controller - Available in multiple coil voltages and contact configurations to match your system - Suitable for standard control interfaces; compatible with AC or DC loads according to model rating - Compact, panel-mountable housing for easy integration - Durable contact material and construction for reliable switching Size and materials - Small form factor designed for tight control panels and enclosures - Insulating housing with robust internal contacts - Built to withstand typical electrical environments with good insulation properties Performance - Low contact resistance for efficient switching - Reliable operation with long switching life - Consistent performance across operating conditions within specified ratings Use scenarios - Home automation: switch lighting or ceiling fans from a microcontroller or smart hub - Industrial control: drive a motor starter, pump, or solenoid in a machine or process line - Building management: control door strikes, dampers, or HVAC relays for centralized systems
