the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 devices u0434u043bu00a0 u0438u0437u043cu0435u043du0435u043du0438u00a0 u043fu043eu043bu043eu0436u0435u043du0438u00a0 functional element in the electric device, such as a magnetic head.in order to u0443u043fu0440u043eu0449u0435u043du0438u00a0 device u043au043eu043du0441u0442u0440u0443u043au0446u0438u00a0 mechanical restraint is such that when the functional element is released from the first working u0438u00a0, it can hold the element in the second position for only a limited u0432u0440u0435u043cu00a0 because its u0443u0434u0435u0440u0436u0438u0432u0430u044eu0449u0430u00a0 power less force of return springs acting on the functional element.to keep the element in the second operating position over a long u0432u0440u0435u043cu00a0, mechanical restraint force created by the mechanical restraint at u0441u0442u0440u043eu0439u0441u0442u0432u043eu043c, may be achieved by additional magnetic retention force acting on the locking device. 3 z. s - lu, 6).
