Questions & Answers

How would you rate this item right now?

It's hard to say. Therefore, it does not contain any electrical components, because I bought it as a decorative feature for a plaque.

Can you tell me how big this item is?

I'd rather not waste my time with it. A size of 3"x4" is probably appropriate. Spend your money on things with value instead of items with little value

This is the DPDT switch to pick up! They were in rough shape when they arrived
3/5

A needle nose plier was needed for all of the contacts to be adjusted correctly. You should be careful not to squish the contacts, take your time. Two of the plastic covers on the terminal nuts were broken, the rest of the covers were of poor quality, and we threw them out. Bolts were easy to replace at the local Ace store due to the good bolt room. In the end, I found this to be a decent switch, especially after spending another $4 and an hour of my time. I use it to switch between the This method works well even though it is fiddly. This is a reliable but flimsy product.

There is useable junk in the world
3/5

It is extra junky and disposable. The thing is worth a dollar at most but I can make it work for the short term. A knife switch would be what you would get if you paid for it with the tickets you earned by playing skeet ball.

This is a cheap and easy to build
3/5

This is not a very good binding post. This is OK for experiments involving low currents. Ok, well. A cheap price. Sadly, I have not found anything that is similar that is well built. Presented in a bubble envelope, and the contacts were bent when it was opened. Bend them back, they are really soft and easy to bend. Binding posts are just plastic head nuts on a bolt with no holes for wires, so if you don't make a loop or put a ring terminal on our wire, it can be difficult to keep it under the screws when I find it useful for things like science toys and homemade electric motors because it uses a low amount of current. The price is not expensive, and there are better switches out there as well, so I might have given it 2 stars if it was more.

This little piece of 19th-century technology is in fact what I needed in order to switch my solar panel input from a controller to a grid tie inverter
4/5

There are two minor issues, however. Although one mounting screw for a terminal was missing, I found a self-tapping screw to fix the problem I had no problems with the tapping screw. Is there something else wrong? Terminal handnuts ought to have a positive and negative color coding of three red and three black, but mine were delivered just like the picture two red and four It was just a matter of applying red paint to fix it. This device is sturdy, straightforward, and simple, and every time I throw it, I feel like Dr. Frankenstein!.

There is no button on the device, even though it's well made
3/5

There is no spring tension on the knife contacts on this device, but it is well made. As you squeeze the contacts, you make connections, but the contacts do not remain connected after they are squeezed. This software is only to be used once.

This is not a commercial grade product
3/5

When I received the switch, the clips were bent and distorted, such that I had to fix them manually Switches like this one are great for the connection of low voltage devices, but I would not recommend them for applications requiring high currents such as.

The quality of the video is poor
3/5

Knobs are cheap and easy to break, which means I will not be using this for my project. On this switch, I would not recommend any electricity be used. Purchase this item at your peril!.

I consider the puppet theater of my wife an indispensable accessory
5/5

My wife's puppet theater needs a DPDT knife switch to turn the stage's lights on and off, so I use the Ajax Scientific DPDT Knife Switch to control the When a puppet is being used, it's easier to push down the switch handle and BAM! The stage is lit. The switch is simple to install, does not require any complex hardware, and is completely This is a great option!.
