Explore a range of relays for electronic circuits, automation, control systems and DIY projects. Relays allow low-power control signals to switch higher-voltage or higher-current loads and are widely used for isolation, switching and remote control applications.
Choose the appropriate relay according to coil voltage, contact configuration, switching current, switching voltage and mounting type. The category includes relays suitable for electronic control boards, microcontroller projects, power switching and automation systems.
How to Choose the Right Relay
When selecting a relay, check the coil voltage, contact type, maximum switching current and voltage, number of contacts and mounting method. Common coil voltages include 5V, 12V and 24V, depending on the control circuit and application.
Relays are commonly used in automation systems, Arduino projects, control circuits, power switching, alarms and electronic equipment. Always verify that the relay contacts are rated for the voltage and current of the connected load.
