Lot of 8 switches From a US supplier. This is the speed control potentiometer that came with your blender. We've sold hundreds of these kits with everything you need to make the repair. This is the same switch you may pay $25 - $30 for from other sellers. 

If your Vitamix (in the variable speed mode) skips speeds when turning the knob you need a NEW variable speed switch.   

The manufacturer charges about $100 plus shipping to fix this part, you can replace it for less than $20.  

This is the switch that was used on the 5000, 5200, VM0101, and other model that has 2 wires.  If you need the 3 wire connection please send a message (switch is the same price) and we will send the 3 wire version. 

Comes with switch, nut, heat shrink tubing and Allen wrench needed to remove drive socket. Printed directions included. 

NOTE: You will receive either the 2 or 3 wire version depending on your request (2 wire is the default).
