Pushbutton Switches are widely used in a variety of applications, and the A3CJ-90B1-12EW is no different. This post looks into what makes the A3CJ-90B1-12EW unique, the application field it’s associated with and its working principle.

What is the A3CJ-90B1-12EW?

The A3CJ-90B1-12EW pushbutton switch is essentially a three-contact snap-action switch, built in both a normally open (NO) and normally closed (NC) configurations. It is often used in a wide range of industrial and consumer applications, such as vending and car button applications, medical devices, TVs, computer mice and gaming peripherals, among other uses.

The switch is compact in size and is available in PCB, panel, or through-hole or surface mount configurations. It offers outstanding reliability, electrical performance, and mechanical robustness for a wide range of temperatures, making it well suited for use in harsher environments.

Applications

The A3CJ-90B1-12EW is primarily used as an on/off switch in consumer and industrial applications. It is commonly used for applications such as power switches, gas tank switches, emergency stop switches, emergency-on switches, shower and tank fill switches, engine cover switches, green-level switches and more.

The switch is also suitable for use in medical applications, such as ventilators, biomedical equipment, and other medical equipment. It is also used in automotive applications such as power window switches, seat manipulation switches, turn signal/blinker switches, starter switches, as well as in appliances such as air conditioners, refrigerators and microwave ovens.

Working principle

The A3CJ-90B1-12EW operates on a snap-action switch mechanism. This mechanism allows the switch to react quickly and accurately to actuate the desired function at the precise time it is needed. SNAP-action stands for ‘snap-on and snap-off’, meaning that the switch reacts quickly and precisely when pressure is applied and released.

The A3CJ-90B1-12EW features a highly durable contact system, eliminating any sparking or arcing on the switch contacts. This helps to ensure reliable and repeatable performance even in challenging environments. The switch also features an improved seal design which helps protect the contacts from dust and any other contaminants from entering the switch.

Conclusion

The A3CJ-90B1-12EW pushbutton switch is a small and robust switch that is suitable for a variety of applications, in both consumer and industrial settings. It operates on a snap-action switch mechanism, providing quick and reliable actuation of the desired functionality when required. The switch has a highly durable contact system, and its improved seal design ensures that it is well protected against dust and other contaminants.
