Figure 1 shows a simple circuit using the MC9S08QE128 microcontroller from Freescale to drive a Finder 40.61.6.005 single-coil latching relay with a standard ULN2003 Darlington driver with open-drain ...

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 ...

HAWTHORNE, Calif.--(BUSINESS WIRE)--Teledyne Relays today announces new wide temperature range, hermetic relays operating up to 18 GHz. The new RF131 and GRF131 single-pole double-throw (SPDT ...

This circuit uses electromechanical relays to retain its state indefinitely, even when power is off. ... K1 is a 5-V dc, dual-coil magnetic latching relay with DPDT contacts.

The latching DW relay from Panasonic has been developed for smart meters, in particular the switching of heater circuit-breakers. Available from TTI, the relays can also be used to minimise standby ...

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 ...

You also get a 3-pin terminal block you can use to wire up whatever you are going to be relay-controlling. Some light soldering is required. Jump cover to the Adafruit website for more details and ...
