Charging socket circuit diagram for battery loco?

[alan2525]

I'm thinking about fitting a charging socket to my IP Jessie and have the socket fitted in the cab. I'd like the socket to break the circuit and just charge the battery without having to remember to switch the loco off first.

Does anyone have a wiring diagram for this? Also what would be the best plug / socket to use?

For one that needs the loco switching off first, yes, but not for what you want, I wasn't aware it was possible to do, might be worth looking at soem R/C plane and boat websites, as they use battery packs and stuff.

Depends on the socket type. I know I'm a newbie here but I'm also a radio ham and electronics enthusiast. A method I use for rechargeables, is to make the on/off switch a changeover, so that in the "off" position it connects the battery to the charger socket, and disconnects the battery from the rest of the circuitry.

Yes, I do that as well.
The other option might be to use a jack plug and socket, with a make and break contact on the socket, but I'm never 100% convinced that the break happens independantly enough to avoid accidents.

You are absolutely correct about sockets, some of their break contacts don't break before connecting the charger into circuit, which is highly risky. If you use switches that are "break-before-make" then its a lot safer.
