Foot pedal device for the operation of a sewing machine and sewing machine with such a foot pedal device

摘要

Foot pedal device (8) for the operation of a sewing machine (1)– with a foot pedal (13),characterized by– a core body (19) with a dipping portion (32) consists of a material with a magnetic permeability, which is significantly larger than 1,– a coil (31), into which the dipping portion (32) of the core body (19) dips,– the core body (19) relative to the coil (31) as a function of the position of the foot pedal (13) is displaceable, so that the dipping portion (32) of the core body (19) in a precisely with the position of the foot pedal (13) correlated depth of insertion (x) in the coil (31) is achieved.
