Ryobi (currently Kyocera) High-Pressure Washer AJP-1620 Micro Switch The terminals of M20-26LBB have been swapped and modified to M20-26LBA specifications. I have tested the replacement. Please investigate whether it can be substituted for other models. This is for DIY use only, so please avoid any difficult tasks. The 2nd and 3rd photos are parts for the AJP1600, so the shape is slightly different. This is a frequently failing part, so it is recommended to keep it as a spare.
