I first heard about and took a look at Relay, a screenless phone for kids back in 2018. The small walkie-talkie device is incredibly simple and easy to use and made it easy to communicate with my own ...

Your smart home shouldn't cause friction.

Aimed at panel builders, system integrators and process control applications, the HF115FP is available in single and double pole versions, rated at 16A and 8A consecutively. Showing versatility, the ...

When we think of relays, we tend to think of those big mechanical things that make a satisfying ‘click’ when activated. As nice as they are for relay-based computers, there are times when you don’t ...

I tested a $15 smart switch and uncovered a $1,500-a-year energy waste in the kitchen ...

I designed this relay circuit to function as a DPDT toggle which is controlled by a momentary switch. I strive to keep my circuits simple with little or no integration (555’s, transistors, etc). The ...

A relay module is an electrical component. Various industries use this circuit board that houses one or more electric switches or relays in different circuits and electrical projects. Relay boards 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 ...

The reed relay was invented in 1936 by Bell Telephone Laboratories. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today.
