FAQ
How does a SPDT limit micro switch work?
The SPDT limit micro switch (single pole double throw) has a common terminal (COM), a normally closed terminal (NC), and a normally open terminal (NO). In the default state, COM is connected to NC. When triggered, the switch action switches, making COM and NO conductive, realizing circuit switching and equipment control.
How many operations can a SPDT limit micro switch withstand?
The mechanical life of a limit micro switch can usually reach more than 100,000 times, and the high-durability model can reach 500,000 times. The electrical life depends on the load. The specific life needs to be determined according to the current, voltage and environmental conditions. For example, the mechanical life of a G12 limit switch is about 200,000 times.
What application scenarios are SPDT limit micro switches suitable for?
This switch is widely used in industrial automation equipment, electric forklifts, machine tools, transmission systems and safety protection devices. It is often used for stroke control, position detection, limit protection and signal feedback to ensure accurate operation and safety of equipment.
Can SPDT limit micro switches be used in harsh environments?
High-quality SPDT limit micro switches usually have IP67 or higher protection levels, are waterproof and dustproof, and are suitable for high humidity, high temperature, strong vibration or dusty environments to ensure stable operation under harsh working conditions.
How to choose a suitable SPDT limit micro switch?
When choosing, you need to consider the operating voltage, current, operating force, travel range and environmental adaptability. If used outdoors or in a high-humidity environment, it is recommended to choose a model with waterproof sealing function and confirm that the load capacity matches the equipment requirements.
