A pulse method to change the state from on to off or vice versa. \\ [[http://www.heathcote-electronics.co.uk/RelayBrd.htm|http://www.heathcote-electronics.co.uk/RelayBrd.htm]] \\ | Latching can apply to both mechanical devices and electronic circuits. |
[[http://www.4qdtec.com/trd.html|http://www.4qdtec.com/trd.html]] | An example of mechanical latching would be a push on / push off switch, [[https://en.wikipedia.org/wiki/Latching_switch|see here.]] See also description of a [[https://en.wikipedia.org/wiki/Relay#Latching_relay|latching relay.]]\\ |
| An example of an electronic latch would be [[https://en.wikipedia.org/wiki/Flip-flop_(electronics)|a flip-flop]] or bistable circuit.\\ |
| A standard relay may be made self latching by supplying a current path for the coil through one of its normally open contact sets. |

[[http://merg.org.uk/merg_wiki/doku.php?id=lcb:start#openlcb_lcc|Layout Command Control]] (LCC) s a system for controlling all the functions on your layout that don’t have to do with how fast the locomotive is moving -- things like signals, or sounds, or passenger car lighting. LCC is NMRANet, just under a different name. LCC is designed as a separate, generic control bus which is positioned to take the load off your throttle bus. It is a bi-directional data bus that can send and receive data. Since it is an NMRA Standard, you are not confined to one manufacturer's products. Any manufacturer can make LCC compatible devices. | [[http://merg.org.uk/merg_wiki/doku.php?id=lcb:start&#layout_command_control_lcc|Layout Command Control]] (LCC) s a system for controlling all the functions on your layout that don’t have to do with how fast the locomotive is moving -- things like signals, or sounds, or passenger car lighting.
