Good as new
Part arrived and replaced with ease. Takes a little time for the part to arrive but this will happen when ordering parts specific to your equipment. Still, $15.95 is a lot cheaper than over $100.
Good job guys!

exact part replacement
i have a Ryobi leaf blower and when i was using it, sometimes the fan would slow down and not blow as hard. I read on line about this problem and most said it was the switch. Sure enough, iI ordered a new switch from replacement parts and its a match. Runs like a new one again. Very pleased.

Pretty easy repair, part works great, like new again.
Had this RYOBI 40v blower since 2019 and it worked fine except at some point this switch went bad and it would only operate wide open and to shut it down you had to take the battery out of the unit. Someone suggested this switch was cheap so for $20 I took a gamble and it works like new again!

Exact Replacement
Just what I needed for my Ryobi Blower. A little tough getting the wires stuffed back into the handle section. Price was good and easy ordering from ReplacementParts website. Would order from them again when needed.

Great factory replacement part, a bit of a tight fit however....
This worked perfectly once installed. Make sure you do not cut the existing wires that connect to this, as you will not have enough slack to connect them. I found it easier to take the entire 2 part handle off, and connect and stuff the wires. Much easier with 3 or 4 hands, and smaller ones at that!

Tool Type
Blower
Difficulty
Hard
Time
1-2 hours
Tools Used
Screwdriver, Pliers, Long T15 Torx screwdriver, wire crimper
Parts Used
Split the case by removing the T-15 Torx fasteners.
A long Torx screw driver must be used to remove some of the recessed screws.
Take picture to document how factory installed the original harness
Removed switch assembly and remover two permanent wire nuts
Installed new switch assembly and installed two new crimp style wire nuts.. It is important to place the wires in the exact same position. I used hot melt glue to secure the wires in the channels.
Do not shorten any of the wires.
Be sure to bend the wires exactly as the original wires or the case will not close completely.
