"Use Save button" in input device ?

[Patou]

Hello,
Can somebody explain what is the action of clicking the "Use Save Button" in the switch device.
I discover with 3 Sonoff 4 CH Pro a strange behaviour :
- All have the same firmware : ESP_Easy_mega-20181220_normal_ESP8285_1024.bin
- All have the same rules
- All have the same devices
Fisrt is working OK
Second reset the outputs 1 to 4 after 4 to 10 seconds to low
Third reset only the ouputs 1 to 2 after same time

I tried to erase all the firmware by loading a blank 1 Mb file no results
Finally I clicked the "Use Save button" and the problem is solved except that the reaction on the input is slower

The Switch Device "Use Safe Button (slower)" feature changes the switch's input sampling from 100mS to 200mS. It is a simple contact debounce.
