Sep 16, 2025
Lub sij hawm Pushbutton, tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm lub khawm hlau laub hloov xws li cov16 hli Hlau khawm hloovLos yog ib LED Hlau Hloov, tuaj yeem tsim cov sib txawv sib hloov hu rau kev teeb tsa kom haum cov ntawv thov sib txawv.
Ib qho kev teeb tsa yog qhov ib yam -} ncej ib {}} pov (SPST). Hauv SPST NTIV TUBBUTON, muaj ob lub terminals. Nws los hauv ob lub sub {{4 4}} Hom raws nws lub xeev ua ntej: Feem ntau qhib (tsis muaj) thiab nquag kaw (NC). Rau qhov tsis muaj -} conte constaged spst lub sij hawm so lub sij hawm, nyob rau hauv lub xeev so, cov neeg tau qhib, thiab Circuit Court tawm.

Qhov no yog dav siv nyob rau hauv cov ntawv thov xws li dov cov dov hlau, qhov twg nias lub pob (kaw lub pob) ua kom lub qhov rooj ntev. Hloov siab, ib qho NC -} conved spst lub sij hawm pushbutton tau raug kaw rau hauv nws lub xeev ib txwm muaj. Thaum lub pob nyem, cov neeg hu qhib, cuam tshuam nrog cov ntws ntws tam sim no.
Lwm qhov tau teeb tsa yog ib qho - ncej ob daim ntawv ob- pov (SPDT). SPDT Mightary Pushbutton muaj peb lub terminals. Nws tuaj yeem hloov ntawm ob lub voj sib txawv.
