## Questions & Answers

**Q: Will fit woods spring count down timer**
A: I'm sorry I'm not familiar with your specific application.  For mine, as it arrived it didn't fit my application. Too small. But I took a drill and enlarged the hole slightly to fit the stem of my appliance and it has worked out fine.

**Q: Will this fit the old style one?**
A: Sorry, I wouldn’t know about your specific item. It actually did not fit my item but I enlarged the hole on the backside with a drill bit and it’s worked very well for quite some time.

**Q: Does this come with the metal shaft?**
A: No. It is just the plastic knob that slips onto the metal shaft of your switch.

**Q: What is the shape of the Shaft?  D?**
A: Yes it is D shaped. Thank you!

## Customer Reviews

### ⭐⭐⭐⭐⭐ I'd buy again
*by K***A on January 22, 2025*

These are great and easy to install. They fit accurately and function well, the only thing is that I thought more come in the bag but that is my fault for not reading the description clearly. I think it's a bit expensive to only have one in the bag and I need to replace 3 of these in my house because my kids turn the knobs to hard the wrong way and break them off. Design is nice and simple, durable if you use them correctly and overall is a good, accurate, timer switch.

### ⭐⭐⭐⭐⭐ Fit perfect
*by L***K on February 18, 2025*

I was happy that it fit the "D" connection on the timer switch

### ⭐⭐⭐⭐⭐ Worked Perfectly On My Timer
*by G***C on February 13, 2025*

I had a broken knob on my bathroom timer and purchased this knob for it. It worked perfectly on the FD series spring wound timer. Looks just like the one that came with the timer. Great buy.
