In addition, the central moving part is equipped with a spring to increase reliability. The manufacturers have provided for the fastening of the magnetic plates in 12 places, six of which are by hammering, to increase the strength of the construction. To reduce vibrations, rubber dampers have been added to the fixed part, and the over-tightened coils prevent the armature from rebounding when the phase crosses zero.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Contacte_auxiliare_NC1\"><\/span>Auxiliary contacts NC1<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In control circuits, where currents and voltages are low, switching can be difficult due to the oxide film on the contacts.
