Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant ...

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 ...

The White-Rodgers SureSwitch™ relay, model number 49P11-843, replaces the function of a contactor and short-cycle timer with a reliable sealed relay. It increases the reliability of air conditioning ...

Figure 1a shows a latching circuit based on an optocoupler, IC 1. If the off switch remains closed, pressing the on switch powers the LED in the optocoupler. Thus, the transistor in IC 1 turns on. You ...

Catalog 1308242, Relays, Contactors, Timers, Transformers and Circuit Breakers for General Purpose Applications is now available from Tyco Electronics. This 480-page catalog describes the major series ...

After seeing an exhibit of an old relay-based computer as a kid, [Simon] was inspired to build a simple two-relay latching circuit. Since then, he’s been fascinated by how relays can function to do ...
