1.Jumpers yog cov hlau txuas hlau uas txuas ob qhov xav tau ntawm lub rooj tsav xwm Circuit Court (PCB). Vim cov khoom tsim sib txawv, cov ntaub ntawv thiab cov tuab ntawm cov jumpers sib txawv.
2. Feem ntau cov jumpers yog siv rau kev sib kis ntawm tib lub peev xwm voltage, thiab tseem muaj cov siv hluav taws xob siv los tiv thaiv circuits. Rau qhov yuav tsum tau muaj qhov ntsuas qhov tseeb, qhov hluav taws xob poob tsim los ntawm qhov me me ntawm cov hlau jumpers kuj tuaj yeem cuam tshuam rau cov khoom lag luam.
