Iimbonakalo:
1.Uyilo olunengqiqo, ukusebenza kohlobo lweqhosha, kulula ukufunda kwaye uqalise.
I-2.Ixesha lokulawula ixesha, ixesha lokucinezela linokusekwa ngokwenkqubo yokuvelisa, kwaye i-plate yokucofa ikhutshwe ngokuzenzekelayo xa ixesha lifika, kwaye kukho i-buzzer yokukhumbuza, ekulungeleyo kwaye ingenangxaki.
I-3.Ixhotywe nge-switch stop stop switch, i-othomathikhi yokukhusela i-stop yokukhusela i-stroke ye-pressure plate phezu komda kunye ne-stop stop switch ejikelezwe ngumatshini wonke, kunye nokusebenza okuphezulu kokhuseleko.
I-4.I-plate ye-pressure yenziwe nge-plate eqinile, kwaye indlela yeoli kwi-plate icutshungulwa ngokugrumba umngxuma onzulu, onezinto ezilungileyo zokuchasana nokuvuza kunye nokusebenza koxinzelelo.
