Steel illuminated push-button with NC (normally closed) contact, for La Felsinea/Sirman slicers, mixers, mincers and bone saws. The housing is made of steel and integrates a pilot light that signals the status of the command; the NC contact stays closed at rest and opens when the button is pressed, the typical configuration used in stop and safety circuits, where opening the contact cuts power to the motor if the button fails or the operator triggers a stop. This is a compatible spare part for the La Felsinea and Sirman control panels fitted on professional slicers, mixers, mincers and bone saws, identified by part code AGWS19410136.10 (ref. AGWSELE2164). A twin variant with NO (normally open) contact is also available — do not confuse the two: always check the machine's original wiring diagram before ordering, to avoid installing the wrong contact. Typical failure signs that call for replacing this button are the pilot light no longer turning on, the contact no longer switching between its two states (staying permanently open or closed), or the machine's stop command no longer responding. Easy replacement, compatible with the original pushbutton panels of the models listed above.
