A five piece kit that enables you to convert your breast shield into a manual pump!
This means for a small extra investment, you get the additional bonus of a hand pump too!
Having the flexibility of a handpump switch kit is very handy if the power goes off and your electric pump does not have an inbuilt rechargable battery like the Allegro and Minuet pump do.
It is also useful to have a switch kit on the off chance you damage a part to your electric pump and need it repaired. The switch kit will enable you to continue pumping while waiting for your part to arrive.
