I've been trying to find a single-row "barrier strip"...
(I'll try to draw one out here)


|O| |O|

I'd like two vertical strips (with screw-holders) seperated.
Most of what I've seen looks like this:


(these connect 2 wires, are available at radio shack, under "barrier
strip")

What do I want to do?
The PB-6 resistor connects 2 contacts on the Curtis.
If the PB-6 is in 'at rest' (non-depressed) position - then it has zero
resistance across the connections.
What I'd like, is a variety of other ways to do the same thing...
basically, short these contacts together.

Push in the clutch? Override the PB-6, thus telling the controller to give
the motor no current.
Transmission in Neutral? A relay pops up and shorts these contacts
together.
Crash sensor? similar thing...
Thus, the controller would be (in each case) instructed (by connecting
these contacts together) to not give the motor any current.

The top section would give me what I wanted...Connect a line from each
'long-row barrier strip' to each contact.
Connect the PB-6 to the first contacts, the clutch switch to the next,
etc....

Anyone know where I can get a barrier strip like this?

I could get 2 of the above models (available at radio shack) and use a
jumper to connect each row...
it would be somewhat kludgy, but it would work.

Suggestions?
I don't want to put a bunch of things in series with the PB-6 microswitch;
I'd rather short these 2 contacts together to shut the controller down.
I prefer this also, to having a safety switch make teh contactor pop-up
when the clutch is depressed... Sure, it'll stop the motor, but the
current going through the contactor will arc, shortening its lifespan.


Thanks!!

Hi Ed,

I think I see what you want to do. Try

http://www.waytekwire.com

Part 47108 terminal block

with a bunch of

Part 37211 jumper strips

Hope that helps.

I had this same problem once... If you look at radio shack, you can get
their "barrier strip" and then a separate piece (I think it's part of a set
for something else but only a couple of bucks) which then jumps to every one
of the screws. So now you have a barrier strip with jumper.

Sorry, it was last year. I don't remember parts numbers but I did get both
parts from radio shack.

Hello Ed,

I find it is best to go to a electrical supply house, set up a account under
Electric Vehicle Research Systems. You do not need a business license yet,
unless you are going to sell these items that you can get at wholesale.

You then can get the General Electric, Westinghouse, Cutler Hammer, Square D
industrial components catalogs which will make your eye ball pop out on all
the type of terminal strips, terminal blocks, power blocks, fuse holders,
fuse indicators, relays, contactors, multi stranded 600 volt wiring that is
design for chassis work, (not the type for conduit).

I use Square D terminals strips blocks that range from 15 amp to 200 amps,
plug in relay sockets, fuse indicators, switches, circuit breakers, etc.,
which are all install on a mounting track to any length you want.

I also like the Power Anderson interlocking wire terminal blocks modules
that can be snap together for any length you want on a mounting rail and you
can just unplug the wire to this strip without using wire terminals, screws
or set screws type of terminal strip.

My EV uses this type of terminal blocks, which may be up to 4 feet long,
where every device in the EV first terminates to this terminal strip first.
Then the circuits are cross connected between two rolls of terminal blocks
to complete the circuit, with LED indicators coming off each mid circuit, so
I can see how the circuit is doing on a display board.

It is very easy to do modifications, replace controllers, or add equipment
by just re-cross connecting this type of connection system, instead running
new circuits or rewiring.

Most of your industrial and aircraft wiring is done this way.
