Also a reflection of 'what the market will bear" design. Such controllers
almost invariably use PCB pattern switches with a rubber membrane with
conductive material that is pressed onto the PCB to make contact. Real
switch failures may often in fact be addressed by pressing harder or
"working" the switch. So pressing harder when the battery is expiring is a
logical action. Adding a key click/beep would provide confidence for such
low cost switches. But probably costs too much :-).
