content: I have one or two circuits that I won't want to use much. Maybe once every couple of months or less.In these cases how can the circuit be connected and disconnected and/or plugged/unplugged when not in use?It would be silly to have to unscrew the wires at the fuse block each time or take out the fuse each time.Could I have it so the +/- wire from the fuse block can go a little way from the main circuit board, to give me access with my hands easily and then some king of pluggable connector so the wire can be stored away when not in use?Are switches appropriate here? It would be ok for one connection I am thinking off, to just keep it off when not using, as otherwise there is always an LED lit up, but in another case, where the rest of the wire run would be several meters, then I would like to stow away that extra wire when not using it.So for the latter case is there a way to make it plug and unplug like you would a usb into its socket? I am not sure what these connections would be called.Am I just looking for general 'connectors'?

content: I don't have a cold but cannot imagine either.Is this AC mains or low voltge dc?What and where is the fuseblock?

content: Quote from: wasedadoc on October 21, 2024, 06:50:38 amLow voltage dc.Well I don't know the nomenclature either yet so that doesn't help.I am just talking about 2 wire connections which come out ofblade fuse block.Looking up on sites it seems things liketheseand respectivefemaleare what I am looking for.So when they are not connected they would take no energy up?

content: For me what is still missing is the information about voltage and current.Do the 12V info that is visible at linked by you 'blade fuse block' is really what you use or this link was only the example and you want to connect to absolutely different voltage (high DC voltages also exists).And different connectors are needed to connect 1mA than 20A and till now I see no information on this subject.To break circuit you can use connectors or switches. In most cases breaking only one of two wires is enough. For example what about switches that are used at AC night light cable?

content: Quote from: PGPG on October 21, 2024, 10:28:07 amI didn't provide those specifics as I was only asking for the general way it is done, as you put in your last sentence.For completeness it is only for low voltage and current appliances on a 12v dc system. Things like lights, laptop, phone. Example case is that I rarely use the phone charger due to hardly ever turning the phone on so wanted the charger I have connected to the fuse block to only make a circuit on the rare times I want to charge it. On the other hand I use the laptop charger daily.

Either one or the other.

content: Oh for <explitive>'s sake! Everything that has been suggested so far doesn't have a strain relief in the plug so wont stand up to repeated handling, and is not intended for 'hot' plugging so to avoid contact erosion, you should switch the power off before making or breaking the connection. Get industry standard 12V accessory sockets for RV/marine use that will stand up to 'hot' plugging, and matching plugs with strain relief, e.g. from:https://www.12voltplanet.co.uk/in-vehicle-power.htmlThe Hella plugs/sockets are more compact and generally higher quality than the lighter socket style.

You can find the same products in any other companies, such as Mouser, Farnel, RS-Components, Element14, etc.As for Terminal blocks themself, this is produced by Degson - it's Chinese company. The same products exists in a myriad of other companies: TE-Connectivity, Molex, Amphenol, Dinkle, Phoenix contact
