endstops doesn't react to switches

Hi, I've got strange problem. I've bought new switches identical to switches which came with the kit. I've soldered them the same way like original switches. I checked if they are working with multimeter and when I click on switch, connection opens perfectly. I've connected them to octopus v1.1 so ground pin connects with signal pin when switch is pressed. When i click the switch klipper doesn't detect it, but when I short ground and signal pins on board it shows that endstop is pressed. I don't know what can cause this. Please help me.
