Thats how home switches are supposed to work.! They hit the switch which triggers the signal state then reverse until the switch releases's and signal changes back to it's original state. Depending how you have them wired IE Normally open (NO) or Normally closed(NC) the signal will go Hi or Low the control software(Mach etc) just watch's for this change.

Wire them NC for safe operation then if a wire breaks or comes lose then the signals lost and machine stops.

The wiring is easy just wire them in series IE + - + - + - + -
