Conventional Reed Switch vs. Bifurcated Reed Switch: What are the Benefits?

In the world of industrial automation, precision and reliability are paramount. The MagPAC product line is designed to meet these demands with cutting-edge technology, particularly in its bifurcated reed switch design. But what sets this innovative design apart from conventional reed switches? Let’s delve into the key benefits and why the MagPAC bifurcated reed switch could be the superior choice for your applications.

Understanding Reed Switches

Before we dive into the differences, it’s essential to understand the basics of reed switches. A reed switch is an electrical switch operated by an applied magnetic field. When a magnetic field is brought close, the reeds inside the switch come together, completing an electrical circuit. Reed switches are commonly used for position sensing, security alarms, and in various types of switching devices due to their simplicity, reliability, and low power requirements.

Conventional Reed Switches

Conventional reed switches have been a staple in various industries for decades. They are known for their simple operation, long life, and the ability to switch low to medium power levels without significant wear and tear. However, conventional reed switches have limitations, especially when dealing with higher capacitance circuits or environments with high in-rush currents. These situations can cause the switch contacts to wear out more quickly or even fail prematurely.

MagPAC’s Bifurcated Reed Switch Design

The MagPAC takes the traditional reed switch design to the next level with its bifurcated reed switch. This design offers several advantages:

1. Exceptional Snap-Acting Breaking Forces: The bifurcated design of the MagPAC reed switch ensures that the switch contacts operate with a snap action. This snap action delivers a quick and clean break in the electrical circuit, minimizing the risk of contact bounce or arcing, which can lead to wear and tear or unreliable performance.
2. Protection Against In-Rush Currents: One of the standout features of the bifurcated switch design is its ability to shield against in-rush currents, particularly those caused by capacitive discharge. In-rush currents can be damaging, leading to premature contact failure. The bifurcated design mitigates this risk by providing enhanced protection, making it ideal for applications involving high-capacitance discrete position feedback.
3. Dynamic Wiping Action: Over time, oxidation and stickiness can build up on the contacts of low-power circuits, leading to unreliable performance or even switch failure. The MagPAC’s bifurcated reed switch incorporates a dynamic wiping action that scrubs the contacts clean each time the switch operates. This self-cleaning action ensures that the contacts remain free of contaminants, enhancing the switch’s reliability and longevity.
4. Precision and Reliability: The design enhancements of the bifurcated reed switch are all geared toward delivering precise and reliable performance, especially in demanding industrial environments. Whether it’s used for monitoring position, signaling, or other critical functions, the MagPAC bifurcated reed switch is engineered to perform consistently over its lifespan.

Choosing the Right Switch for Your Application

When deciding between a conventional reed switch and a bifurcated reed switch, the choice largely depends on the specific demands of your application. Conventional reed switches offer simplicity and cost-effectiveness, making them suitable for many standard applications. However, if your application involves high capacitance, potential in-rush currents, or requires superior contact reliability, the MagPAC bifurcated reed switch provides significant benefits that can enhance performance and extend the operational life of your equipment.

By choosing the MagPAC with its advanced bifurcated reed switch, you’re not just selecting a switch; you’re opting for a solution that delivers precision, durability, and peace of mind in even the most challenging environments.
