MA04L2NCQD

Rotary Switches

MA04L2NCQD is a type of rotary switch developed by Mars Airlife Company. This switch is suitable for a variety of applications that require frequent manual intervention. It is also popular in applications where the switch is used to select or activate multiple functions or positions.

Application Field

MA04L2NCQD can be used in a wide range of applications including control instrumentation, signal acquisition and transmission systems, building automation, power systems and automotive industry. In addition, it has been widely used in security systems, electronic locks, surveillance systems and fire safety devices.

MA04L2NCQD is particularly suitable for applications with high resistance to dust, moisture and vibration. Its superior construction ensures high durability and long working life even when subjected to harsh environmental conditions. Its tight tolerance and wide contact gap make it suitable for reliable performance in a variety of operating conditions.

Working Principle

MA04L2NCQD works by using sequential contacts, each of which is actuated when the switch is rotated. This means that when the rotation limit is reached, the switch will automatically switch from one position to the next. Consequently, each contact can be used to control a single function or multiple functions as required. Also, this switch is equipped with built-in limit stops which allow for limited rotation angles to be selected so that different functions can be easily selected. This makes MA04L2NCQD ideal for applications requiring a wide range of operation angles.

MA04L2NCQD also features a wide range of actuators, the most popular being a key, knurled knob, push button, toggle lever, toggle arm and rocker. The actuator type chosen depends on the application and the length/size of the switch required. In addition, the switch is designed to eliminate noise and is shock resistant, making it suitable for even the harshest of environments.

In summary, MA04L2NCQD is an excellent choice for a variety of applications requiring frequent manual intervention. Its ability to cope with harsh environments, wide range of actuators, precise and smooth operation and long working life make it ideal for use in control instrumentation, signal acquisition and transmission systems, building automation and power systems.
