Toggle switches play an important role in a plethora of applications. due to their versatility, toggle switches may be used in various devices and machines, ranging from hand-held devices required for switching and control functions to large industrial machinery. the 26ET66-T series of toggle switches are an ultraminiature solution designed to fulfill the growing demand for reliable micro-miniaturized toggle switches. This article will discuss the application fields and working principles of the 26ET66-T series of toggle switches.

What are the 26ET66-T Toggle Switches?

The 26ET66-T series is a range of ultra-miniature toggle switches designed to provide cost-effective micro-miniaturized solutions in various environments. The series provides a variety of switches with a range of standard options such as panel, surface, and board-mounting; two or three poles, single and double throw (SPDT and DPDT) configurations; solder, quick-connect and other termination options; momentary and alternate configurations; and many other features. The toggle switches are available in both through-hole and surface-mount packages and are rated for up to 16 amperes (amps) at 125/250 volts.

Application Fields

The 26ET66-T toggle switches are typically used in a variety of media and devices, from commercial and industrial machinery to hand-held instruments. The series is particularly suitable for miniature applications needed in medical, automotive, telecommunications and home appliance electronics, as well as industrial and military applications. The rugged construction and versatile design of these switches make them great for remote operations and control applications. The through-hole and SMT packages make them suitable for integration into a wide range of printed circuit boards (PCB’s) and industrial equipment.

Working Principles

Toggle switches, like the 26ET66-T series, operate on the principle of a break-before-make mechanism. Basically, this means that the switch opens one contact before closing another. This is necessary in order to avoid short-circuiting the device and causing potential electrical damage. The toggle switches are single-pole-single-throw (SPST) switches that use a lever arm to open and close the switch. The lever arm is spring-loaded and connected to an internal contact mechanism, which creates an electrical circuit when the switch arm is engaged. The contact can also be adjusted from a normally open (NO) to a normally closed (NC) position, which allows the user to program the switch for different applications.

In addition, the 26ET66-T toggle switches have an enhanced design that ensures repeatable and reliable operations. They feature double-wiping contacts and silver-nickel terminals, which extends the life of the switch and eliminates contact bounce caused by mechanical shock and vibration. The switches are also sealed construction, which makes them dust-proof and water-proof, making them suitable for harsh or hazardous environments.

Conclusion

The 26ET66-T Micro-Miniature Toggle Switches provide reliable and cost-effective solutions for a wide range of applications. Their small size, rugged construction, and versatile design make them suitable for a variety of environments, from industrial and military to home appliance and medical equipment. The break-before-make contact mechanism, double-wiping contacts, and silver-nickel terminals ensure reliable switch power ratings up to 16 amps and terminate in solder, quick-connect and other termination options. With their versatile design, the 26ET66-T Toggle Switches are a perfect choice for adding functionality to a wide range of applications.
