I had put a Push/Push pot in my semi-hollow body guitar to split my humbuckers. It was a pain in the neck to do the rewiring in that type of a body. The switch worked for about 15 minutes and then it wouldn't stay in the down position. I had to take the pot back out and put a Push/Pull pot in to get it work right. I took the Push/Push pot apart and found that the switch design was not adequate to withstand heavy daily use. My advice is - Stay away from the Push/Push pot. It is susceptible to mechanical failure. It costs more than the Push/Pull pot but it does not have any advantage over the it.
