A bag of bits to deal with , someone thought epoxying a SM switch back onto
the pcb was enough and then could not reassemble the Chinese block puzzle. I
managed to work out how to get the meshes back into the mic housings and the
2-mic cross- yoke assembly back into the main body, despite never seeing the
original disassembly sequence. As the usual incompetent "designer" , no
point in replacing as "designed". This sw is only soldered at the usual SM 3
miniscule pads to the pcb with no extra moulding around it to resist any
excessive finger pressure.
So come flat battery and nothing at switch on , the usual owner thought
process is press the button harder.
Oddly there is quite a bit of space to play with and a larger switch can go
in there , mechanically decoupled from the pcb via 3 wires of course, but
I'm wondering what sort of fixing. 2 screws through the body to properly
anchor some mount behind a bigger more conventional stemmed click switch ?

I forgot the important point, these switches are soldered side-on to the
board not large face to the board , so a turning moment of half-width times
finger pressure to break the solder

Orange silicon dimple cut from inside a scrapped R/C zapper , with the
conductive pad cut away, seated in the casing hole and larger thru-pcb click
switch mounted inside it, fixed to the case , not the pcb. Wired to the pcb
pads, Looks better than the original , and beneficially now more recessed
and hopefully will last longer than the original

A bit disconcerting on first powering up, not seeing how these operate
normally.
Needs 3 second hold down on the momentary sw or just a brief line on the LCD
and brief flash of the backlight and peak LED.
There will be thousands of these abandoned by owners , for anyone who finds
one and is prepared to get inside and do a fairly simple repair,
