Connex Switches
Has anyone had any experience with the Connex switches from the Parts Connexion? I'm looking at buying their 4x24 switch to build an attenuator, and and their 4 pole six position switch to use as a source selector.

They seem cheap as chips when compared to the other options offered, and with the exception of the Electroswitch I can't afford the more expensive options for the attenuator right now. Why is there such a large price difference, and is their anything that I should be concerned with if I go with this option? How are the others better? The alternative would be to go with an alps blue or noble volume pot for now, and then to save up for something like a Shallco or Elma down the road. If necessary, I could stretch for a more expensive source selector right off the bat. Thanks for all of the input!

Here's a link for the source selector. Part number Connex 75573 i think.
ConneX 2 Deck, 2 Pole/Deck x 6 Position, Silver-Plated, Non-Shorting (BBM)

Here's a link for the attenuator switch. Part number Connex 75502 i think.
Connex Rotary Switch, 4x24

Thanks for the advice.

They look like generic Chinese switches. Might be a bit cheaper from ebay, e.g.:
4P 24 Step Rotary switch Attenuator Volume Control DIY | eBay
4Gates 6 Step Rotary Switch Volume Control Selector DIY | eBay

Can't say about quality, haven't used mine yet. They're going into one of Richiem's notch filters eventually. I think he used similar switch types in his own unit:

Thanks for the identification EssB. Can anyone comment on the differences between these generic switches and the more expensive Shallco's or Electroswitch's? Do they tend to sound worse, or is the difference one of longevity, or tactile solidity? Would I be better off going with a pot at this price point? I found a link to a similar switch that has more specs.

Is there a strong reason to spend more when my non-chassis budget for a passive pre is in the 100-150 dollar range?
