Kunezinhlobo eziningi ze-lefoo pressure switch zokunqamula i-air compressor ezitholakala emakethe. Kumkhiqizi we-pressure switch, Ukukhetha ama-pressure switch afanele e-air compressor kuncike ekutheni uhlelo lokucindezela umoya luyini. I-pressure switch entsha ivame ukunemba kakhulu kunokulungisa eyakudala, kuyilapho ama-pressure switch amadijithali angalungiseka ekunikeza ukusebenza kalula uma uwasebenzisa.
Ama-pressure switch e-air compressor anengqondo enziwe yi-LEFOO pressure control ayizinto zokulinganisa, zokubonisa, nokulawula umfutho. I-air compressor cut-in kanye ne-air compressor cut off switch ingalawula ngokuzenzakalelayo ukuphuma kwe-relay ngokusho komfutho osepayipini. Uma kuqhathaniswa neswishi yemishini, inezici zokusebenza okulula, ukubonisa okucacile, ukumelana nokuthuthumela, nokunemba okuphezulu kokulawula.
Uma i-compressor ixhunyiwe ohlelweni lwe-air compressor, injini iyaqala futhi i-air compressor iqala ukucindezela. Uma umfutho oshiwo wohlelo ufinyelelwa, i-relay izolawula izintambo zikagesi zihlukane, inqamule isekethe futhi imise injini. Njengoba umoya usetshenziswa futhi umfutho wethangi wehlela ezingeni elithile elishiwo le-‘cut-in’ (cishe ama-PSI angu-30 ngaphansi kwesethingi le-‘cut-off’), izintambo ze-relay ziyavaleka futhi injini iqala kabusha. Umjikelezo uyaqhubeka inqobo nje uma i-air compressor cut off switch isetshenziswa.
