The smaller size, the more difficult to make it in high quality, but MQS-9A is the micro switch that is not only ultra subminiature but also sealed structure. Because of its high quality, it is used in automotive parts, like the car door lock EKT. You may see from some car side doors inside. This is the SPST normally open circuitry mechanical switch that is the momentary reset type from OFF to ON. So, it will be used as a signal switch in the device.

Meanwhile, the Min. electrical life of the MQS-9A is 300000 cycles, if you use it 10 times a day, the switch can last 82 years. How many times your car door will close and open?

Besides, it has various parameters for customer options, please contact us for model selection.
