Snap action, limit switches are instruments that serve as emergency stops, amongst other uses. Whilst the specific application fields, and the working principles, of a given limit switch type may vary, the D2MQ-1L-105-TL model is a micro switch, an electromagnetic switch type. This article outlines its primary application fields, and its working principle.

Application fields:

The D2MQ-1L-105-TL limit switch has a number of potential application fields, due to its versatile nature. Examples include its use as a safety stop or warning signal in control panels, controlling motor starters, conveyors, and industrial devices in general, as part of automatic control systems, and its common use as a part of devices that open circuit when the contact limit has been reached.

Working principle:

The D2MQ-1L-105-TL limit switch is an electromechanical switch: an electrical circuit is opened or closed by mechanical action. This is achieved when a movable contact in the switch is either pushed, under the influence of a force such as gravity or a spring, or pulled across physical contact by an internal force such as a magnet or an electromagnet. To restore the system, a spring must be reintroduced in order to close the contact.

The switch is fitted with a wide range of actuating levers made of Ferrous Steel or plastic, allowing the user to set a wide range of parameters. Designwise, the lever of the switch is designed for different designs, depending on the application field. The user may select the appropriate lever design according to the features required.

To further increase safety, the switch is shipped with a clear cover nut, which prevents contamination when it is free from any foreign objects. Additionally, the push-on type switch is fitted with a built-in lock button to ensure against unauthorized contact closure.

To increase its long-time practice, the switch can be used in environments whose temperatures range between -25 and + 70 degrees Celsius, ensuring its extended use in any given application field. Furthermore, the pressure resistance of the switch is tested at 1,000,000 times without fail, allowing it to function consistently in case the switch is subjected to large stress.

All in all, the D2MQ-1L-105-TL limit switch has a wide range of applications and working principles, making it a very versatile device.
