Thank you. This was the solution to the on/off switch sticking in the off position. Cleaned and greased the stem and spring as shown and the K2 is back in business! Its well work fixing as I felt there wasnt that much wrong with it.

Good, couldn't find any other video explaining this.

Very informative 🌟👍
