Hom WE tswj li qub yog solenoid ua haujlwm cov lus taw qhia spool li qub. Lawv tswj qhov pib, nres thiab kev taw qhia ntawm qhov ntws. Cov kev taw qhia li qub no yeej muaj cov vaj tse (1), ib lossis ob lub solenoids (2), kev tswj cov spool (3) nrog rau ib lossis ob qhov rov qab springs (4). Nyob rau hauv qhov xwm txheej tsis ua haujlwm, tus tswj spool (3) yog tuav hauv nruab nrab lossis thawj qhov chaw los ntawm qhov rov qab springs (4) (tshwj tsis yog cov detent spools). Tswj spool (3) yog actuated los ntawm ntub-pin solenoids (2). Lub zog ntawm solenoid (2) ua los ntawm plunger (5) ntawm kev tswj spool (3) thiab hloov nws los ntawm nws thawj txoj hauj lwm mus rau qhov xav tau kawg. Qhov no ua rau qhov xav tau ntawm kev khiav, P mus rau A thiab B rau T lossis P rau B thiab A rau T. Tom qab solenoid (2) yog de-energized, tswj spool (3) rov thawb rau nws txoj haujlwm pib los ntawm kev rov qab los. caij nplooj ntoos hlav (4). Phau ntawv override (6) tso cai rau tswj spool (3) kom txav tsis tau lub zog solenoid.
