I'm looking for a place to buy a DPDT 30VDC 3A rated On-Off-On switch in/near Auckland CBD tomorrow, needed to switch a 30v 3A DC motor from FW-off-RW.

Jaycar have this however it doesn't specify DC rating so I'm reluctant to try it as have already blown up a couple of 240v AC switches and relay's aren't really an option: http://jaycar.co.nz/productView.asp?ID=ST0575

Tried Surplustronic and Dick Smith but no luck.

Ask Jaycar for the specs, they are owned by an electronics component distributor and should be able to get you the specs.  Or http://nz.rs-online.com/web/ if you are willing to pay the price they charge (make sure the stock is local before you go there, often it is in Sydney or further away).




You can never have enough Volvos!

What is the motor?  You probably need to deal with the reverse EMF or else you will blow most switches even when rated for the operating current.

Looking at RS online now. I noticed delivery ETA for some items I was looking at were either 2 or 5 days so assumed shipping from NZ or AU.

Do you know if they allow pickup from their 'warehouse' in Penrose?

Don't have the exact specs of the motor, it's driving a gear unit on a standing desk. I'm replacing the two SPDT mom-off-mom rockers (when need to be used in unison) with one DPDT on-off-on switch so I can have it auto max raise/lower.

Turns out a marine electrical shop is the best place for DC electrical gear.

http://www.electricsafloat.co.nz/ by Vic Park were really helpful and had just what I needed.

Element14 are pretty good.

 

 

I don't think they hold stock in NZ but I've ordered from them once and that order was delivered the next day from Sydney.

 

 

Their pricing on their website is in NZ$ and plus GST. Delivery is free if over is over $45 (I think) and I think the charge for delivery under $45 is something like $15.

RS is also excl GST, but fast.  You can pick-up from Penrose.  I prefer E14 though, wider range of the stuff I use.  Glad you got sorted, good idea to use marine switches as they are designed for reliability...
