Description

Proximity switch for pedal capable of preventing starting during power failure Technical Field The utility model relates to the technical field of shuttle cores of sewing machines, in particular to a proximity switch for a pedal, which is powered off and prevented from starting. Background The proximity switch of the pedal is an electronic switch capable of detecting the position or action of the pedal without mechanical contact, the proximity switch triggers signal output by sensing the proximity degree of a target object (such as the pedal), the core principle is based on the technologies of electromagnetic induction, capacitance change, photoelectric effect or ultrasonic reflection and the like, and when the pedal approaches to the sensing surface of the proximity switch, the sensor detects the change of magnetic field, capacitance or light intensity, thereby outputting the on-off of an electric signal control circuit; However, when the common proximity switch for the pedal is used, when the shuttle core is replaced, the cover plate needs to be opened, the equipment is powered off to play a role in safety protection, and if the pedal is stepped on by the staff carelessly, the pedal can be started to cause accidental injury, so that a further improvement room is provided; Therefore, we propose a proximity switch for a pedal for power-off prevention start-up so as to solve the above-mentioned problems. Disclosure of utility model To solve the problems set forth in the background art. The utility model provides a power-off starting-prevention proximity switch for a pedal, which has the characteristics of changing the common proximity switch for the pedal, opening a cover plate when a shuttle core is replaced, ensuring that the equipment is powered off to play a role in safety protection, and starting the equipment to cause accidental injury if a staff steps on the pedal carelessly, so that the room for further improvement is provided.
