Snap Action, Limit Switches are normally open or normally closed switches used to detect the presence or absence of an object. The D2MQ-4L-1-R Limit Switch is a double pole, triple throw (DP3T) mechanical actuator with a single position. It consists of two double-pole, double-throw micro switches and one single-pole, single-throw micro switch, mounted on a body. It has a single isolated action and is designed for use in actuator controls.

The D2MQ-4L-1-R Limit Switch is designed for a wide range of applications, such as material handling, circuit protection, industrial automation, and medical equipment. Its double pole double throw (DPDT) nature allows for multiple actions to occur depending on the configuration of the switch. For example, in an industrial automation application, the single position might be used to stop a conveyor belt and the DP3T switch might be configured to activate a warning light, sound an alarm, or other action.

The working principle of the D2MQ-4L-1-R Limit Switch is relatively simple. The actuator, which can be anything from a roller to a lever, is activated when an object comes into contact with it. This causes the contacts on the switch to close, inducing a current. When the object is no longer in contact with the actuator, the contacts on the switch open, breaking the circuit and stopping the current from flowing.

The D2MQ-4L-1-R Limit Switch begins its operation in the normally closed (NC) position. This position keeps the power source and loads disconnected until some external force is applied to the actuator, which operates the switch by closing the contacts. This supplies power to the load and shuts off the power source. The amount of force necessary to operate the switch is adjustable by means of a set screw.

The next position is the normally open (NO) position. In this position, the contacts are open, disconnecting the power source and the load until the actuator is activated. This position is commonly used as a warning or control circuit in industrial automation applications that require precise control of the power to a load. The adjustable set screw and contact pressure settings of the switch allow for the desired response time and force to be set for the application.

Finally, the single pole, single throw (SPST) switch is used for the third and final position. This switch is usually used for auxiliary operations, such as indication, signalling, and control. For example, the auxiliary switch can be configured to trigger a warning light, sound an alarm, or other action when the actuator is activated.

The D2MQ-4L-1-R Limit Switch is an excellent choice for a wide range of applications. Its single position, multiple switch configuration make it ideal for precise detection and control of a variety of objects in a wide variety of industrial automation applications. Its adjustable set screws allow for precise control of the force needed to operate the actuator, as well as the response times, making it an ideal solution for precise control in applications that require precision.
