Precision micro switches usually have three specifications: basic type, type with operating handle, type with operating handle and shell type.
5 Key Features to Consider When Buying a Micro Switch !
- 1) Outline Dimensions – Because the switch size is directly related to its characteristics, including current range, stroke and operating force.
- 2) Electrical Requirements [Voltage/Current] – Micro switches are typically capable of breaking current from 5mA/5VDC~25A/250VAC
- 3) Reliability [Mechanical/Electrical Lifetime] – A reliable micro switch can operate 10 to 20 million times before mechanical failure
- 4) Environmental Factors – Know the environmental conditions of the application, including contaminants in the air that may enter the switch, the liquid the switch is in, and operating temperature requirements, etc.
- 5) Agency Certification
