Snap Action, Limit Switches: D3V-16-1E6 application field and working principle

Snap action and limit switches are usually electromechanical devices used to detect the presence or absence of electrical conditions (e.g., on/off switching) or to sense the physical position of objects. The D3V-16-1E6 switch is a subminiature snap action and limit type switch.

Application Field

The D3V-16-1E6 switch is widely used in consumer electronics such as motor-driven household appliances, computer control systems, and office automation equipment, as well as in the industrial control and automotive fields. The contact of this switch is capable of handling a maximum carry current of 0.5A at a maximum rated voltage of 125V AC, and 10,000 electrical lifetimes. Its small size and high-temperature rating make it a suitable choice for applications in high-temperature environments. Due to its extremely small size, it can be easily installed in places which are difficult to access. This is why it is often used in space-saving office automation equipment, motor-driven household appliances, instrumentation and control equipment, as well as in various industrial and commercial applications. The D3V-16-1E6 switch is of great utility in various industries, making it a very viable choice for a wide variety of application fields.

Working Principle

The D3V-16-1E6 switch uses a snap-action mechanism that utilizes a mild but spring-loaded ball sliding across the contact surface of an arc supporter to achieve an instantaneous momentary closing or opening of the contact. When the actuator is pressed, the ball is ejected onto the arc supporter by a spring. Escaping the spring’s lever arm, the ball accelerates rapidly and forces the contact to open or close according to the required switching action. Once the actuator is released, the ball is returned to its resting place, completing the switching action and restoring the switch to its original state.The contact can also be held in open or closed position by using a shift lever or a position stop mechanism. The action of the switch is extremely fast and highly reliable, making it suitable for use in situations that demand uninterrupted operation.

Conclusion

The D3V-16-1E6 switch is a reliable and efficient snap action and limit switch. It is suitable for use in motor-driven household appliances, office automation equipment, industrial control and automotive applications due to its robust construction, small size, and high rated current and voltage. The snap-action operation of this switch enables it to provide reliable and quick switching at an economical cost.
