Working Principle

The working principle of the 38HM90 switch is relatively simple. It is a single-pole, single-throw (SPST) snap-action limit switch that utilizes a snap-action micro-switch mechanism. This mechanism operates by detecting when a predetermined limit or threshold has been reached and then activating or deactivating the associated circuit. The resulting switching action occurs almost instantaneously, meaning it is both reliable and highly responsive. It is also noteworthy that the 38HM90 can be easily constructed in a wide variety of different operational formats. For example, it can be produced in an adjustable version which allows for the range of the switch’s activation to be set prior to its use. This adjustable feature makes the 38HM90 highly versatile and suitable for use in a wide variety of settings.

Conclusion

The 38HM90 snap action limit switch is a device designed specifically for use in delicate and high-performance settings. It utilizes a snap-action micro-switch mechanism to detect and respond to predetermined thresholds or limits. This device is also highly versatile and can be produced in a wide variety of different versions, including an adjustable version. All in all, the 38HM90 is an effective, reliable and versatile type of limit switch perfect for use in the field of household appliance, medicine and other demandingly-precise applications.
