SwitchBot Replacement Arm Parts Only (5 pieces) *SwitchBot main unit not included. Made of aluminum for excellent durability! Just replacing this will revive your SwitchBot! "Can't push anymore" is not an option! It's safe to replace the resin arm before it breaks! 3D printed parts are also made of resin, so they will eventually break, but this is made of aluminum, so it's okay! No need to buy a new main unit unnecessarily! High-precision hole that perfectly fits the D-shape of the motor shaft. It firmly receives the rotation of the motor and can press the button with a strong finger. Since there is no groove to hook for switch mode, those who are using it in switch mode cannot use it. *Multiple pieces available for sale 2 pieces: 1250 yen 3 pieces: 1800 yen 4 pieces: 2350 yen 5 pieces: 2900 yen We will list multiple pieces if you contact us separately. Each piece is cut out by cutting from unprocessed aluminum plate, so there are polishing scratches from the drill bit overall, but there is no problem at all in use. Please understand that this is a handmade product by an individual before purchasing. Returns and exchanges are not accepted.
