Snap action, Limit switches are mechanical devices that are used to sense a physical position or the motion of an object. They are commonly used in machine and motion control applications. The D4BS-2BFS is one such switch, and is widely used for a variety of applications. This article will provide an overview of the D4BS-2BFS application field and its working principle.

The D4BS-2BFS is a single-pole double-throw (SPDT) snap action switch. It has three terminals, namely, common (C), normally open (NO) and normally closed (NC). The switch is specially designed for low current and power applications. It offers fast and reliable switching operation due to its combination of mechanical snap action and an electric actuator.

The switch offers two different actuator choices:Top Actuator: This is a plunger-type actuator that is pushed against a coil spring when actuated. The coil spring provides the necessary force to operate the contacts.Side Actuator: This is a lever-type actuator that is actuated by rotating it beyond a certain angle. This causes the contacts to move very rapidly, resulting in a quick change in state.

The D4BS-2BFS is ideal for applications such as motor speed controllers, time relay, contactors, and over-current relays. It is also used in vending machines and automatic door openers. It is also widely used in electrical appliances such as refrigerators, air conditioners, washing machines, microwave ovens, and other electric circuits.

The working principle of the D4BS-2BFS is quite simple. When an electrical current is applied to the switch, the electric actuator forces the contacts to change their state. The contacts remain in their new state until the current is removed, at which point the contact springs back into its original position.

The D4BS-2BFS is designed and manufactured to ensure reliable and long-term operation. It is made from corrosion-resistant materials and has a long operational life due to its self-cleaning design and low contact resistance. The switch can also be customized to meet specific application requirements.

In conclusion, the D4BS-2BFS is an invaluable device in a wide range of applications. It is designed to provide reliable and long-term operation, quick response time, and accurate measurements. With its broad application field and simple working principle, it is no wonder that the D4BS-2BFS is a popular choice for those who require reliable switching solutions.
