Snap Action Limit Switches

Snap action limit switches are a type of mechanical position sensor based on a spring-loaded mechanism. Such switches can be used to detect the movement of an object along one or two axes, or the presence of an object in the vicinity until it reaches the end-stop. These switches are usually triggered by a switch actuator, which is a small spring-loaded actuator. When an object enters the space between the actuator and the switch contacts, the actuator compresses and trips the contacts, turning the switch on or off.

DB1CB1LB snap action limit switch consists of a micro-switch, an adjustable mounting bracket and an actuating element. It features a uniform operating force and superior repeatability, and it is designed to withstand up to 10 million operations. It has a travel of 1.5mm and a standard operating force of 5N, although other forces are available. The switch is also waterproof and dustproof, making it suitable for many applications. The mounting bracket has 4 mounting holes, making it easy to install in various applications.

Applications

The DB1CB1LB snap action limit switch is widely used for detecting the position of objects or the levels of fluids. Examples include elevators, conveyor systems, packaging machines, and door openers. Due to its robust design and excellent operating force characteristics, the switch can also be used in harsh industrial environments, such as industrial workshop, foundries and other places with high humidity and dust level.

Working Principle

When the DB1CB1LB snap action limit switch is actuated, the switch contacts close or open depending on the movement of the actuator. The two switch contacts in the DB1CB1LB switch are connected to two wires. When the actuator is actuated and the switch contacts close, the current flows through the wires and can be used to power up a device or trigger an alarm. The spring loading of the actuating member ensures that the switch returns to its initial position after the actuator has been released.

Overall, DB1CB1LB snap action limit switch is a robust and reliable switch suitable for a variety of applications. Its adjustable mounting bracket and low actuation forces make it a perfect choice for demanding applications. It is also waterproof and dustproof, making it a good choice for outdoor applications.
