Hi I don't mind the cheap switches personally, so long as i am careful it saves me quite a bit of money - 50p a switch. Operation wise they are fine, but you do have to be careful when soldering - I have melted a couple before. I agree the push switches they sell at Maplin are good quality. Another thing I have noticed from the cheaper switches is that the fixing nuts can be really poorly made, or even rusty.
The toogle switches are the same, the cheap ones melt really easily but operation wise they are okay. Again the type they sell at Maplin are okay but well over-priced. I think they are Talco and the sell them at Rapid too. Generally I use the better components when I am bending something more worthwile, and use the cheaper components when I am messing about, making prototypes or it is the first time I have bent a particular model. It's so depressing when you have spent ages bending something and spent money on good components only to fry it, tread on it, or ruin in some other careless way
