Simple smartphone example uses instant message on web applications like social messengers, creating evolution in the Industrial Era. Starting with the basic application of switching the buttons or relays ON or OFF which shares information through different software made for switching analysis. These switching analysis is majorly used by actuators or any different machine parts, sensors which are connected with Wireless push notification contact closure through wired or wireless network to create communication.

After observing about many push technology solutions for Industry 4.0 revolution for the wireless sensor network, the great and trusted product of NCD is the Long-range push notification contact closure which has the capability to work under the private topology IEEE(802.15.x.x) standards. It sends the notifications of different and complex types of machinery switching process through wireless mesh network, consisting of small box with antenna using 2.4 GHz frequency with 2 AA batteries with 500,000 transmissions using minute power consumption or long lasting battery life cycle of 10 years with some conditional process, can send the continuous data regarding machinery switching system to PC’s which are connected with endorsed company modems work as receiver. The receivers which receive the switching status from these wireless transmitters using mesh network policy without any interference and display it on "N button" software, specially designed by the company to monitor the status or input and output.

These solutions are not only ended with a specific recommendation but have also greatest effect to connect with famous IOT platforms via Micro-controllers like Arduino, Raspberry Pi, Particle and many other development boards platforms which can easily connect through online database servers like Azure, Google firebase, AWS(Amazon) and many more. It stores the information securely and display it on our smartphones or email addresses also or by using special protocols like MQTT , Twilio etc. will helps the users to automatically receive the text messages or phone call to receive the notification through GSM or CDMA sim communications, commonly available with every person for calling or texting purpose at the time of unavailability of internet connection.

Nowadays push notification hardware are easy to connect through cellular communication controllers also like Particle Electron, Lora gateway, Pycom etc. which has the features to communicate the wireless Push notification hardware directly to communicate through the application servers which sends the important notification regarding actuators switching status or sensor status at the remote locations where wifi network is not available.

These notification contact closure devices nowadays useful in several industries to test power input as well as output, digital sensor monitoring, Industrial pulse detection, garage door alert system and also easy to be customized as per users expectation while designing with alert parameters. Using wireless push notification technology of dry contact closures transmitters to test the switching of different output or input as well as wet contact closures can also detect the DC as well as AC input and output, with the feature of automatically sleep when no input will be detected without any special coding requirement. Well, for better factual knowledge to make it useful with designed software NCD provides manual on their website with a nice explanation which helps users to make it work easily.
