Re: [PolySix] Switch replacement

2003-09-29 by greg montalbano

Yes;  desolder the LED, then it & the switch cap will come off, then the 
switch itself can be desoldered & removed.  Take care in handling the 
switch caps -- once the plastic breaks, they're difficult to repair (& 
impossible to replace, as far as I know).
I've obtained suitable replacement tact switches from Mouser Electronics & 
Jameco -- they're fairly standard.
This is a fairly routine task for someone with soldering & electronics 
experience -- should be VERY carefully approached by anyone else.
