Sustitución de llaves

   En muchos aparatos se utilizan llaves separadas para conectar la alimentación, principalmente en los casos en que las corrientes consumidas son elevadas (amplificadores, toca- cintas, etc.). Con el uso, la corriente excesiva puede calentar los contactos, causando incluso el derretimiento de la llave o la inutilización de los contactos. En este caso, debemos sustituir la llave por otra del mismo tipo. Una llave con mayor capacidad de corriente también puede ser utilizada.
