Electronic micro switches find applications in a wide range of industries and systems. They are commonly used in home appliances, such as refrigerators, washing machines, and microwave ovens, to detect the position of doors, buttons, and other components. In industrial automation, micro switches are utilized to provide limit and position sensing, ensuring accurate and safe operation of machinery. They are also essential in automotive applications, where they are employed in indicators, power windows, and various safety systems.
Electronic micro switches are designed to operate in challenging environments. They are engineered to withstand various temperature ranges, ensuring their functionality in extreme heat or cold conditions. Many micro switches also have ingress protection ratings, making them resistant to dust, water, and other contaminants. These rugged features make electronic micro switches suitable for demanding applications in industries such as aerospace, marine, and industrial manufacturing.
Environmental requirements have a strong impact on the choice of microswitches, especially in applications such as industrial controls and medical devices that require high reliability and criticality. Understand the environmental conditions of the application, including contaminants in the air that can enter the switch, the liquid in which the switch is located, and the obligatory temperature requirements.
How many electrical and mechanical operating lifes do you need to understand for an application? Different switches have different contact materials, housings and terminals to meet the electrical and mechanical life requirements of different applications.
The power-on and reset keys on the chassis are both micro switches. The left and right mouse buttons are all micro-motion buttons; the optical drive eject buttons are also micro-motion buttons.
The nudge switch is not in place, please reconnect it to the expected position. Continuity testing; If the micro switch is in the expected position, the above continuity test is performed by attaching a voltmeter to it.
GB/T19001-2008, ISO45001:2004, BSOHSAS18001:2007, QC080000 , IATF 16949.
