Chipangizo choteteza kugwedezeka chimawongolera mafunde amagetsi monga mafunde otulutsa mphamvu kuchokera ku dera lalifupi. Chimachita izi pogwiritsa ntchito solid-state contact kapena air-gap switch. Kuphatikiza apo, chipangizo choteteza kugwedezeka chimagwira ntchito ngati chipangizo chotseka mphamvu kuti chizimitse mphamvu yamagetsi pamavuto amagetsi komanso chobwezeretsanso mphamvu yamagetsi pamwamba pa magetsi ovoteledwa kapena magetsi otsika ngati vuto litachitika. Tingagwiritsenso ntchito chipangizo choteteza kugwedezeka pamlingo uliwonse wa netiweki yamagetsi. Njira imeneyi nthawi zambiri imagwiritsidwa ntchito kwambiri komanso yothandiza kwambiri poteteza kugwedezeka kwamagetsi.

Chipangizo choteteza mafunde chomwe chalumikizidwa motsatizana chimakhala ndi kuletsa kwakukulu. Mwanjira ina, kuchuluka kwa kuletsa kwa mndandanda kumakhala kofanana ndi kuletsa kwa chipangizo chimodzi choteteza mafunde. Kupitirira kwa mphamvu kwa nthawi yochepa kukaonekera mkati mwa dongosolo, kuletsa kwa chipangizocho kumachepa, kotero mphamvu ya mafunde imayendetsedwa kudzera mu chipangizo choteteza mafunde, kudutsa zida zodziwikiratu.
