Snap action, limit switches are mainly used for monitoring and controlling the displacement of mechanical parts. D5A-8515 is one of the most commonly used snap action, limit switches. This article will explain its application field and working principle.

One main application of the D5A-8515 snap action, limit switches are controlling the travel distance of automatic mechanical systems like robot arms, production line servo motors and automatic lathes. This switch is able to accurately adjust the maximum displacement distance, allowing the robot arm, servo motor and the automatic lathe to travel no further than the set distance by detecting the displacement position. This type of switches use an external actuator to rotate the rocker arm and contact to the corresponding point and can be equipped with high voltage, high current and dust-proof electronic switches.

In addition, the D5A-8515 operation is stable and reliable. It utilizes a low-friction switch mechanism that does not need manual reset and can resist shock and vibration. Moreover, the switch contacts are made of high-durability copper alloy that can last for a long time and provide consistent performance.

The working principle of the D5A-8515 snap action, limit switches is quite simple. It is designed with a snap-acting mechanism which has an actuator that is attached to a rocker arm. When the switch is activated, the actuator will push the rocker arm to reach the specified displacement point, thus activating the switch. Inside the switch, there is an electrical contact where the rocker arm makes contact with when the displacement is reached, allowing electricity to flow through, which then triggers the switch. This mechanism works in the same way for the free-rod, extended-rod and rodless versions of the switch, providing reliable electrical engagement and contact.

In summary, the D5A-8515 snap action, limit switches have many uses and an easy-to-understand working principle. These switches are ideal for controlling the travel distance of automatic mechanical systems, as they are able to accurately adjust the maximum displacement distance, provide reliable electrical engagement and contacts, and last for a long time.
