An electrical relay is a type of heavy-duty, remote-control switch able to handle high-current accessories, yet capable of being actuated by substantially less current. Relays install between the ...

When you are used to working with semiconductor devices, the data sheets for relays may pose some problems. What do terms like ‘Operate Voltage’ and ‘Release Voltage’ mean, for example? When you are ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...
