Review: Bien - Acabo de instalarlo, así que no puedo opinar del artículo en su uso a largo plazo. Puedo decir que viene bien presentado, y con toda la tornillería, y que parece robusto. Los tornillos de los terminales que salen en mis fotos no son los del artículo, de serie viene con garras para cable pelado, y yo los cambié por tornillos M6 para usar terminales redondos en las puntas de los cables. Sólo echo en falta la posibilidad de quitar la chapa de aluminio que indica la posición del conmutador "1 0 2", cosa que sí de puede hacer en otros conmutadores de este tipo, permitiendo poner una rotulación personalizada (por ejemplo, en mi caso sería "Fuente 220V - Desconectado - Dinamo locomotora". Pero vamos, esto no es determinante.
Review: Superb quality. Very well engineered. - Superb quality. Very good unit.
