This is a simple clap switch circuit with high sensitivity. The only unusual component is the single coil latching relay. While there are numerous means of generating the latching function, the ...

Control applications often requirethat you set a relay latch in positionuntil you need it to change state.Latching relays accomplish that task.When you send them a pulse, they eitherremain in the ...

Several years ago, Paul Rako, in collaboration with the late, great Bob Pease, wrote a terrific article about the finer theoretical and practical points of electromagnetic solenoid-driver circuits. 1 ...

As automotive engineers continue to implement more electronics on vehicles and tighten specifications and expectations for high reliability, the venerable mechanical relay has become endangered. A new ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.
