Snap action, limit switches, such as D4SL-4MDG-DN, provide reliable, accurate switching and long life performance in many applications, due to their robust and precise designs. The snap action actuates faster than most mechanical switch contacts, with a wide range of operating forces available to select the most suitable mechanism.

The switch is actuated in the same manner regardless of the gap between the target and the actuator. This consistency allows the same switch to be used in multiple applications, even where the gap varies. For example, when pulling on a cable, the switch can remain in a constant condition, as the gap between the actuator and the target changes.

Switching speed is a key factor for many applications. D4SL-4MDG-DN can achieve operating speeds of less than 20ms. This minimises the time the switch is in motion, reducing the abrasive wear, heat accumulation and fatigue.

The D4SL-4MDG-DN operates on a simple electromechanical principle. When the switch is triggered by an electrical signal, the armature inside the switch is lifted away from the stationary contact and brought into contact with a different electrical contact. This creates a closed circuit and allows electricity to flow. When the energising voltage is turned off, the armature is released and the two contacts separate, opening the circuit. This causes a break in the current flow, typically resulting in a momentary power outage.

The switch is constructed of a polyamide case, brass or stainless steel, and a PBT armature. The contact is gold coated, providing a robust and low contact resistance and a long life. The body contains a lever mechanism, which ensures a long life expectancy due to its precision in design. The switch is also insulated, meaning it is completely safe to use, as there is no risk of risk of electric shock.

D4SL-4MDG-DN can be used in a wide range of applications, including industrial, automotive and medical. The switch can be used to trigger a circuit when pulled, to create a timer when it is released, or to detect a change in position, for example, a door opening. In industrial applications, the switch is used as limit switches on automated machinery, to modify signal paths and alert detections of dangerous situations.

D4SL-4MDG-DN offers reliable, accurate switching and long life performances, making it the ideal choice for a variety of applications. Its snap action design, precision mechanisms and insulation guarantee a safe and reliable switch. The robustness, flexibility and long life make it a reliable choice for many applications.
