Possibilities of using a triangular-shaped current in an inductance coil in devices for reversing neutron polarization (flippers) are considered. Tests of the flipper with a triangular-shaped current on the neutron beam demonstrated that the efficiency of neutron spin flipping is not worse (within a measurement error) than the efficiency of a flipper with a sinusoidal current. It was shown theoretically and confirmed in practice that setting (switching on) and drop (switching off) of the current in the coil can happen "instantly" (with an accuracy of up to a period) in response to switching-on and switching-off of the control signals.
