Time relaychishandiso chekudzora chinoshandisa electromagnetic musimboti kana mechini musimboti kuwana nguva yekunonoka kutonga. Iine marudzi akawanda, akadai semhepo damping type, yemagetsi mhando uye yemagetsi mhando. Nguva inodzokororwa inogona kukamurwa kuita mhando mbiri: ine simba nguva yekunonoka mhando uye simba-kudzima nguva yekunonoka mhando. Mhepo-yakanyoroveswa nguva relays ine yakakura kunonoka range (0.4 ~ 60s uye 0.4 ~ 180s), iri nyore muchimiro, asi kushoma kwaro.
Kana iyo coil ichinge yasimbiswa, iyo armature uye mapallets zvinokwezvwa nepakati uye inofamba ichidzika ipapo, ichiita iyo pakarepo chiitiko chekubata pa kana kudzima. Asi tsvimbo yepiston uye lever haigoni kutevera armature pamwe chete nekudonha, nokuti iyo yepamusoro yepiston tsvimbo yakabatanidzwa kune membrane yerabha mukamuri yemhepo, apo tsvimbo yepiston mukubudiswa kwechitubu yakatanga kudzika pasi, rubber membrane pasi concave, kamuri yemhepo pamusoro pemhepo inova mutete uye tsvimbo yepiston inonyorova uye zvishoma nezvishoma inodonha. Mushure meimwe nguva yenguva, iyo piston tsvimbo yakadzika kune imwe nzvimbo, inosundidzira kunonoka kubata chiitiko kuburikidza nelever, kuitira kuti iyo dynamic break yekubata ibve, ine simba yekubata yakavharwa. Kubva pane coil yakasimbiswa kusvika kunguva yekunonoka kubata kuti upedze chiitiko, ino nguva inguva yekunonoka yekudzosera. Hurefu hwenguva yekunonoka hunogona kuchinjwa nekugadzirisa saizi yemhepo yekamuri yekupinza gomba ine screw. Mushure mekunge coil yekukwezva yabviswa-simba, iyo relay inopora nekuita kwechitubu chekudzoreredza. Mhepo inokurumidza kubudiswa kuburikidza neburi remhepo.
