More mileage out of your Oral B Pulsar toothbrush

Step 9 The modification

Many posts on the web on this subject suggest playing around with the contact to try and get the switch to work properly. Personally I didn't have the patience. The following works just as well for on/off operation in my opinion and is a lot less hassle.

Bend the tab on the contact backwards and squeeze it down as close as you can get it to the contact. By doing this you will effectively remove the on off switch from being usable.
