Snap action, Limit Switches are generally used in applications which require a simple mechanism to control a large or small electric current or voltage. These switches can be used as contactors, relays, or switching mechanisms in electrical and electronic circuits. The D4V-8166Z snap action, limit switch is a single pole, single throw, momentary contact switch, with a travel range of 0.6 mm and an adjustable full-on-off travel of 1.5 mm.

A D4V-8166Z snap action, limit switch is composed of several elements, including an armature, contact, actuator, and a housing. The armature is the most important element of the switch. It is made from metal which has been treated to minimize oxidation, and is also designed to provide smooth, consistent action. The contact is tungsten-alloy and is designed to maximize conductivity while minimizing arcing. The actuator, which functions as the on-off switch and is the actuator responsible for the switch’s micro-switch capability, is composed of a spring and a plunger. Finally, the switch’s housing is designed to minimize the risk of contamination.

When an in-phase voltage is applied to the terminal of the switch, the mechanical actuator inside is triggered and moves an armature which in turn moves a plunger. As the plunger moves, it creates a non-contact electromagnetic field, which is sensed by the switch’s contact. When the plunger and the armature reach their full-on positions, the contact closes, thus completing the circuit and allowing current flow. When the plunger deactivates, the armature retracts and the contact opens, interrupting the current flow.

The D4V-8166Z snap action, limit switch is ideal for automotive, electrical, and industrial applications due to its ability to quickly react to voltage changes and its lightweight design that enables it to be mounted in tight spaces. It is also suitable for use in robotics and motion sensing systems, as well as in home appliances, including light switches and washing machines. The switch can also be mounted to a variety of surfaces, including walls and ceilings, thanks to its NEMA type 3 mounting holes.

The D4V-8166Z snap action, limit switch offers exceptional reliability and precision. Its precision spring mechanism ensures quick and accurate responses to voltage changes, while its durable construction and long-lasting performance make it an excellent choice for high-demand applications. Additionally, its dust- and waterproof design makes it ideal for outdoor and industrial use.

In conclusion, the D4V-8166Z snap action, limit switch is well-suited for a variety of applications due to its combination of high-precision operation, absolute reliability, and lightweight design. Thanks to its durability and excellent performance, this switch is sure to withstand the rigors of any application, from robotics and industrial to automotive and home appliance applications.
