Small and micro touch button 2 * 3 * 0.6 ultra-thin mold switch with tape and disc installation, micro travel limit switch is a commonly used small current master electrical appliance. By utilizing the collision of moving parts in production machinery to activate their contacts, the control circuit can be connected or disconnected to achieve certain control objectives. Usually, these types of switches are used to limit the position or stroke of mechanical movement, causing the moving machinery to automatically stop, reverse, change speed, or automatically move back and forth according to a certain position or stroke. In electrical control systems, the function of limit switches is to achieve sequential control, positioning control, and detection of position status. The internal structure of the micro button switch used for controlling the travel and limit protection of mechanical equipment is roughly different from the structure of the toggle switch, but in a different form. Another thing is that it has many unique characteristics, such as the flexible movement of the slider compared to other switches. This indicates that its switching speed is very fast, because we know that as a switch, if we have already pressed the switch, but due to the inflexible movement of the slider, it may cause some unnecessary trouble if the power cannot be turned off in a timely manner. The other thing is that it has stable performance, which means that it is very stable in use, and there will be no Glitch or problems.
