Wiring a battle switch

hi all

some of you may know i am going to build a crusher fw, i bought from technobots a battle switch and a relay to use the contriol for the crusher. im not ready to wire them yet but just need to know how, can anyone help? more details on each can be found below

the relay is the 24v one

thanks alex

Youll want two relays Alex.... one for extending the linear actuator and one for retracting it.....configured like this ...http://www.teamonslaught.fsnet.co.uk/DPST.gifhttp://www.teamonslaught.fsnet.co.uk/DPST.gif

Im probably going down the Battleswitch path for controlling my crusher too and Im after the FWD-OFF-BACK control for my actuator; would I not be able to achieve that with just the battleswitch on its own? Or do I need the two relays as Woody described, as well as the battleswitch? (Ive never fully grasped the concept of how many/what relays Id need for controlling different weapons)

Cheers,
Jamie

If you use a simple ON / OFF function R/C Switch ....like I believe the Battle switch to be .... then you wont be able to give the crusher the OFF function.
Youll only be able to get FWD ( extend to crush ) when you activate the Battle Switch and REV ( retract and return to the ready position ) when the Battle switch is OFF.

You really want a Robbe - Duo - Switch unit #83192000 or similar to activate some larger amperage relays.
You can then get your required 3 functions.

Oh! ....and youll also want a couple of microswitches to act as limit switches.
Im happy to knock up a wiring diagram if anybody requires one.

yes please, i dont know if you know woody but the battleswitch has 4 screw terminals if you could could you include which wire goes to which terminal?

thanks alex

Id welcome a diagram as well (cheers Woody!!) but having just had a quick glimpse on Technobots, Im toying with the idea of getting a Dimension Engineering Syren 10 Motor Controller (http://www.technobots.co.uk/acatalog/Online_Catalogue_Dimension_Engineering_Controllers _34.htmlhttp://www.technobots.co.uk/acatalog...gineering_Cont rollers_34.html) to control the linear actuator since, as far as Im aware, its a relatively low current-drawing actuator (2A I was told when I bought it) and that controller adds up to a similar cost to the Robbe Duo unit plus relays.

So I might give the motor controller a try and see how it performs

EDIT: Any luck getting an actuator for your crusher yet Alex?

Youll need to give me some idea of the notation on each of the four terminals.

NC - NO - BAT .....Etc.

ok they are ...

s1
sc
s2
nc

it gives some info

s2 to neg bat
sc to neg motor
s1 pos motor then pos bat

well im in contact with linak and have contacted other companies but no luck yet
thanks alex

If you want to run a motor with three options - forward, reverse and off - get an Electronize electronic switch from Technobots and make a 2 relay H bridge to go with it. The battle switch will only give you on and off.

Well Alex as I said ..and confirmed by John in the post above ....you really want a different R/C switch.

Jamies speed controller idea is probably the better option .. then all you need is two limit switches with diodes placed across the contacts.. opening the microswitch breaks the supply going to the motor ..thus stopping the linear actuator over travelling.. and the diode ensures that the reverse direction can still be obtained.

Or you can do as I do and get a linear actuator thats already got the limit switches built in :mrgreen:

well thats slightly annoying, im sure someone suggested a battleswitch, does anyone know if technobots take products back? will check the website anyway

hopefully i will also get a actuaor with limit switches in

alex

im sure someone suggested a battleswitch

Yup ......Jamie did back at the beginning of October.

Im just using a servo microswitch system at the moment but the battleswitches on Gimson Robotics would probably be fine (I think youd need two)

Those battleswitches are great for switching big relays for heavy duty disk weapons in a single direction for instance.

But when it comes to working in 2 directions, a dual rc switch like the Robbe 8445 dual is the best way to go. They are pretty cheap as wel (28 euros in holland, so about 19 pounds i guess).

*whistles innocently*

Sorry about that Alex, at the time I genuinely thought it could be used to control an actuator in an FWD-OFF-BACK arrangement but it was only a few days ago I realised that the relay of a battleswitch was just an on-off type.

Paul at Technobots might take it back, or if not, put it up in the For Sale section if you have no other need for it and someone might take it off your hands.

Again, sorry about the wrong info

Jamie
Your quote posted by me includes that in RED .....where you rightly say I think youd need two.... and you could manage to control the actuator with two relay switches that worked in opposition off the same stick.
So ....It would really appear that its not your wrong info

Ahh, thank you Woody for bringing that to my attention - I didnt even notice the red! (better get my eyes checked)

In that case then, me saying I gave Alex the wrong info is incorrect, but its safe to say my information could have been interpreted as being misleading :)
(hope you manage to return/sell/make use of your battleswitch though)

well seems i got the wrong end of the stick there, luckily jonno says he will swap it for an electronize switcher WILL THIS WORK?????? can someone just give me a yes or no answer so there isnt any confusion.

thanks alex

An electronize electronic switch will work fine and it has a built in failsafe too. Depending on how much current you are pulling you might need to make a relay H bridge for it (which is easy - two SPCO relays and some wire) but you can probably get away with wiring your crusher direct to the electronic switch - it depends on how much current you draw.

YES

yes

ehh.... pass. :)

Yes

thanks for that, if i get the actuaor i am currently thinking of it will draw 7a a full speed, so will the electronize need SPCO relays?

alex

Electronise dual switcher should handle 10 amps.

The 48B-2Way switcher is up to 10A, the 4Way is 3A per relay. So assuming you get the 2 way switch from Jonno you will be fine.
