Minimum switching load, voltage, utilization category, conductor range and <strong>terminal torque<\/strong> must come from the exact accessory documentation. A physically similar switch can have a different current range, temperature limit or electrical endurance. Check the manufacturer compatibility list before specifying either format.<\/p>\n<p>Electrical endurance and mechanical endurance describe different duties. Estimate the expected switching frequency and load type for the <strong>control circuit<\/strong>, then compare them with the exact accessory rating. An endurance figure is not a calendar-life guarantee. Repeated switching of an inductive load requires the appropriate utilization rating and any suppression specified by the manufacturer.<\/p>\n<p>For a PLC input, maximum contact current is not the only acceptance criterion. Request the minimum reliable switching load, input wetting-current requirement and the control-circuit voltage. If the manufacturer does not declare reliable low-level operation, obtain a suitable interface rather than assuming that a high-current contact will work consistently at a very small signal current.<\/p>\n<figure class=\"article-image\" data-image-slot=\"body-1\">\n<img decoding=\"async\" alt=\"\u0644\u0648\u0627\u0632\u0645 \u062c\u0627\u0646\u0628\u06cc \u0631\u0627\u0628\u0637

ordinary auxiliary contact is not automatically a safety-rated interlock or proof of electrical isolation. If the application requires a safety function, the responsible designer must specify the required architecture and matching component evidence. For routine status monitoring, separately label a lost control supply or broken wire as an unknown state where the control design permits it, rather than mapping every missing signal to a healthy
