Good product but non-standard pin spacing.
Pin spacing is non-standard. One way it is .2" but the other way it is .25. They CAN be used on a .1 in. grid, but only by bending the pins. See photos. You might be able to push them into a breadboard block but the pins really are not made for that. The pins are not round. The thickness is OK but they are .04" wide. I don't know any kind of perf or pcb with a pin spacing that isn't a square grid. Otherwise the product is good. The 2.1 mm dimension mentioned in the product description is the diameter is the inner pin.

A few dollars for a switch verses a new pump at over $200. no brainer!
Exactly what i had to have to repair my HVAC vacuum pump;

Pins are too wide.
The connection pins are too wide to put into a through-hole SMT PCB board. Had to bend them over and solder wire to them to work.

Use in Breadboards? No. But nice third solder-tab secures nicely to avoid twisting
Unless the seller is talking about nailing the things to a 1950's style, wooden breadboard, it's not clear where the “Breadboard-friendly” assertion comes from. The three tabs are made to be soldered into circuit boards, and I could not force them into any modern breadboard. I used a rotary tool to grind all three narrower and twist two of them so they'd be oriented properly to fit into the breadboard. Even then, needing to twist two of them shortened them too much for the breadboard to hold them well. On the plus side, I like that the sockets have three tabs to be soldered into the circuit board to keep it from twisting when plugging in a power supply.

I love these positively beneficial barrel jacks! They are also breadboard compatible as well as being soldered to a printed circuit board. Amazing!
