En estado sin tensi\u00f3n, los contactos permanecen en modo normalmente abierto (NA), y las patillas 30 y 87 est\u00e1n desconectadas; cuando se aplica la tensi\u00f3n nominal al terminal de la bobina, el mecanismo electromagn\u00e9tico funciona para hacer que los contactos m\u00f3viles y est\u00e1ticos se cierren, y las patillas 30 y 87 conducen para formar un circuito. Tras un fallo de alimentaci\u00f3n, el mecanismo de restablecimiento por muelle restablece autom\u00e1ticamente el estado normalmente abierto, realizando una r\u00e1pida interrupci\u00f3n del circuito.<\/p>\n\n\n\n<h3><a href=\"https:\/\/topfastpcba.com\/es\/5-pin-relay\/\">\u00bfQu\u00e9 es un rel\u00e9 de 5 polos?<\/a>?<\/h3>\n\n\n\n<p>El rel\u00e9 de cinco contactos es un rel\u00e9 electromagn\u00e9tico de tipo unipolar, doble tiro (SPDT) que permite la conmutaci\u00f3n bidireccional del circuito con la acci\u00f3n sin\u00e9rgica de los terminales de control de la bobina (85, 86) y los terminales de contacto (30, 87, 87a).<br>En comparaci\u00f3n con los rel\u00e9s de cuatro patillas, los rel\u00e9s de cinco patillas pueden satisfacer necesidades de control m\u00e1s complejas con su capacidad de conmutaci\u00f3n de doble circuito y sus caracter\u00edsticas de realimentaci\u00f3n de estado, y se utilizan ampliamente en sistemas el\u00e9ctricos que requieren conmutaci\u00f3n multiestado o protecci\u00f3n contra fallos.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Structural_Design_and_Functional_Differences\"><\/span><strong>2.
