Review on πŸ”„ Highly Optimized Single-Position Rotary Selector Switch by Brandon Ball

Revainrating 1 out of 5

Not 4P3T switches, kinda weird 1P12T

These aren't 4P3T switches, although I'm not even sure what to call them. There are 4 rods but 12 throws. But only 1 rod is active per throw, so only 1 rod circuit is used in each position. Instead of 3 switch positions where each ABCD center pin corresponds to 3 output pins (you know, every true 4P3T switch in the world), there are 12 switch positions. This means it's more like having 4 independent switches in one box, where only 1 switch can be activated at a time. I can't even think of how to use them unless I wire 4 poles together and then have a 1P12T switch (maybe it's time to do that discrete EQ I was thinking of hmmm ). For those interested in matching: Pos. 1: Contacts A and 1 are closed, all contacts are open. Pos. 2: Contacts A and 2 are closed, all other contacts are open. Pos. 3: Contacts A and 3 are closed, all other contacts are open. Pos. 4: Contact B. to Contact 4 is closed, all other contacts are open. Pos. 5: Contacts B and 5 are closed, all other contacts are open. Pos. 6: Contacts B and 6 are closed, all other contacts are open. Contacts C and 8 are closed, all other contacts are open. 9: Contacts C and 9 are closed, all other contacts are open. 10: Contacts D and 10 are closed, all other contacts are open. 12: Contacts D and 12 are closed, all other contacts are open. The fact that they are listed as 4P3T is a blatant lie, although there are 4 poles in the switch the best description I can find is 1P12T as no poles can be activated at the same time.

Pros
  • Industrial switches
Cons
  • No power
