选择微动开关的五个关键特征

选择正确的微动开关时, 以下五个关键特征不容忽视: 构成因素, 电气要求 (电压/电流), 可靠性 (机械/电气寿命), 环境因素 (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, 和操作力. Although this tiny switch is suitable for detecting circuit conditions in a compact circuit breaker, it typically only breaks 0.1 到 3 amps (一种) 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 (交流或直流) are required when the micro switch is selected for the specific application.

Feature 3: 考虑环境条件. You need to choose a sealed switch with a wide operating temperature range for harsh environmental applications. 同时, 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, 加拿大cUL认证或CSA认证, 欧洲ENEC认证, and CQC certification in China.

Feature 5: Defining the working life requirements A highly reliable microswitch can operate 10 到 20 million times before mechanical failure and operate 50,000 到 100,000 电气故障前最大负载次数. 不同的开关有不同的触点材料, housings, and terminals to meet different applications’ electrical and mechanical life requirements.
