oh i understand now.
just a bit miffed when i noticed the VAT on technobots for the battleswitch was 17.5%, i guess thats what we get for voting in cameron.

[RogueTwoRobots]

No, that's what we get for living in a country where VAT has been 17.5% for quite a few years now :P
Now that Cameron's in, it will be rising to 20% from 4th January 2011.

Just a word of advice; a battleswitch turns something on and off (in some cases, such as yours, through a bigger relay). So that means you can turn your axe motor on (fire forwards) and off. But you need to return the axe so you will need another battleswitch to turn the motor on in the other direction (axe return).

Based on Technobots prices, a battleswitch costs £19 inc tax, so for two that would be £38. But they also stock a Doubleswitch, which is a dual battleswitch for £25 inc tax, saving yourself £13:

It is a double-pole, double-throw switch, which is needed to control a motor in a fwd-off-back manner, so connecting this up to two larger relays should provide you with the ability to both fire and retract your axe.

[elobire]

thanks, do you have any recomendations for 2 larger relays?

[RogueTwoRobots]

Can do, although using large relays for weapon control is an area that I've not really had to delve into yet, so another forum member will probably be able to make a better recommendation as to which type to get.

In order to get an idea of what relay to use, can you provide a link to, or some information about, the motor you will be using for your axe?
