Пять ключевых особенностей выбора микропереключателя

При выборе правильного микропереключателя, следующие пять ключевых особенностей нельзя игнорировать: фактор формы, электрические требования (напряжение / ток), надежность (механическая / электрическая жизнь), факторы окружающей среды (hazardous environment, temperature range), and agency certification.

Feature 1: Understanding the dimensions of the switch The size is essential when choosing a micro switch. Switch size is directly related to its current range, travel, и рабочая сила. Although this tiny switch is suitable for detecting circuit conditions in a compact circuit breaker, it typically only breaks 0.1 к 3 усилители (А) of current and has a short travel.

Feature 2: Understanding electrical requirements Micro switches typically break current from 5mA/5VDC to 25A/250VAC. The micro switch product line offers a range of products from low energy to power load electrical for various applications. The rated current and voltage (переменного или постоянного тока) are required when the micro switch is selected for the specific application.

Feature 3: Учитывайте условия окружающей среды. You need to choose a sealed switch with a wide operating temperature range for harsh environmental applications. В то же время, it is also important to note that the degree of protection of the switch should be at least IP67 to prevent liquid ingress.

Feature 4: Defining the working life requirements Choosing switches that meet various international electrical requirements can help you simplify product design for different regions. Some major standard certifications include UL certification in the United States, Сертификация cUL или CSA в Канаде, Сертификация ENEC в Европе, and CQC certification in China.

Feature 5: Defining the working life requirements A highly reliable microswitch can operate 10 к 20 million times before mechanical failure and operate 50,000 к 100,000 раз при максимальной нагрузке до электрического сбоя. Разные переключатели имеют разные материалы контактов, housings, and terminals to meet different applications’ electrical and mechanical life requirements.
