Question

hi i would like to make a base with a on/off switsh like in pic,would this work ?

Dunning-Kruger · Answer

No... you forgot the battery

Nomad 6R · Answer

hi RR this is from the base,so it would not disconnect the power. cause the power of a batt will go thru the circuit board allreddy ?

DJ Sures · Answer

Haha nooooooooooooo do not do that! That is a switch to short the battery. Uhm, it's a bomb - actually

Nomad 6R · Answer

hi dj i was thinking off possible danger,thats why i ask. so changing this with the board from jd chest would be a solution, to ad a on/off switsh on the base.?

You need to find a different spot to put the switch. Look very, very carefully at that board Patrick, like with a magnifying glass if you need to. Notice how on one side of the board is discolored line that goes from the two bottom terminals in the power plug all the way up the side of the board (where is says EZ-Robot) and over to one side of the mini deans connector? On the other side you can see a discolored line that goes from the other side of the mini deans connector down to one side of the fuse, then a gap, then it picks up again on the other side of the fuse and leads into the back pin of the power plug. Do you see it? Those are circuit traces. They replicate wired connections on the circuit board. If you could cut or interrupt one of the traces and splice in a switch, that is where you could add a switch. What I would try if I were you is: Desolder the power plug (all 3 pins) so you can remove it. Then bend up the back pin so that it will not make any contact with board. Then reconnect the plug by soldering the front and side pins back in place. Then connect your switch between the end tab on the power plug and the fuse tab closed to the power plug. **Take care to ensure the connection has no change of shorting! Then - Test your connections for continuity with a volt meter set to "continuity or diode test". Flip the switch one and off and make sure the correct continuity shows for on and off states. - IF NOT - recheck your work. Then - test with a battery connected to the power plug and a volt meter on the mini deans connector to insure voltage shows being turned on and off correctly. **Make sure your tests past before you every plug an EZB into something modified!

thanks justin for this explanation. yes i did see it.i think for me is just change the board with one off jd's chest,

cem · Answer

@Nomad, you could always just remove the fuse and put the switch in series with the fuse. Don’t ever put a switch between the + and - of a supply, you will short the battery out!

hi cem thanks for the info.like in the pic ?

cem · Answer

Yes, but I would put the switch first and then the fuse.

JustinRatliff · Answer

So to keep the fuse you'd desolder the holder for fuse then run wires from the fuse holder. Unless you want to solder the fuse inplace.

Nomad 6R · Answer

just to be sure i can solder direct on the fuse pads,see pic cirkel.

Nomad 6R · Answer

ok here it is ,the base with on/off switsh. also it would be nice to have a batt case.

kamaroman68 · Answer

That yellow fuse is rated at 20 amps. Highly doubt those switch contacts are. Nomad be careful

Nomad 6R · Answer

The fuse original is 20 amps yellow.

Nomad 6R · Answer

its same switsh as jd body.?

Nomad 6R · Answer

are these desame on/off switshes as used by ez robot ? on/off switsh

DJ Sures · Answer

great work! looks good - i can't tell from the image, but it would be a good idea to run the fuse in circuit closer to the battery, and the switch after it. Just for safety... but i'm sure it's fine like that

Thanks dj
