Hello.. great product.. was please with the whole deal .. we will be back.. good day
Quality unit, exceeding our expectations. Unfortunately it was damaged in shipping but Marine Parts Only had us a replacement in just a weeks time. :)
Product specifications match my needs. Delivery and cost were competitive.
Hey guys, it is so good to find a source for high quality toggle switches. I didn't pay close attention and ordered a momentary on switch first, of course I will keep it for later use. I immediately ordered the standard on/off switch and had it in no time.
The quality is fantastic. When they say sealed, they're serious. The quality can be felt when push the lever.
The rating of 50,000 operations insures I won't be replacing it anytime soon. While I only need switches for occasional projects, when I do need one, I will definitely be ordering from you guys.
Thanks, Keith Vining
Prompt, no hassle experience; the right parts arrived when promised at a very reasonable price. I’ll sail with them again
