LS-30 Switch Service
- Snap ring pliers
- Home-made top cap removal tool
- Socket wrench with 10mm socket
There's a simple way to get the handles off! I don't think I would have figured this out without this forum post.
The outer sleeve part of the switch assembly shaft unscrews from the base. In order to protect the shaft from marring I wrapped it in several layer of electrical tape before unscrewing it with a pair of pliers.
Once the case is open you can remove the contact carrier, circuit board and click mechanism (not official names). The circuit board is secured to the case but comes off with a little gentle prying (I said gentle). Be very careful removing the click assembly under the circuit board as it contains several tiny parts that are easily lost (two springs, two small metal plates, and two cylindrical rollers).
The grease had dried up and the blue upper housing had started to wear. As well, smell flecks of metal had worn of the shaft and made their way into the switch.
