The Ultimate Guide to Inching Feature

What is the Inching feature

First thing first, many of you may ask “what the heck is an inching switch?” Inching is also called jogging. The definition of jogging or inching by NEMA is “the quickly repeated closure of a circuit to start a motor from rest for the purpose of accomplishing small movements of the driven machine.” In short, this kind of switch allows you to turn it on for a short time. That’s also why sometimes it is also called a momentary switch. 

In the past, eWeLink Support devices include physical inching switches, which have higher requirements for background knowledge on the users. You must be very familiar with DIY and comfortable with wiring. However, this is such a useful type of switch that we realize we should make it easy to use for everyone. 

Therefore, we released the inching feature for our regular plugs and switches. This feature changes your normal switch into a virtual momentary switch.  It allows you to turn on your connected device for a preset duration ranging from 0.5 seconds to 3600 seconds (1 hour).

Where To Use It

1.Auto-off Scenarios

Even though schedules and timers are very useful to control devices at preset timing, they can not meet the demand for turning off devices automatically each time the device is turned on, regardless of how it is activated. Considering that you cannot set a scene with the same device being the condition and action, the inching feature is the best option for you. 

Exhaust Fan

You can enable the inching feature on a switch connected to an exhaust fan so that it turns off in 3 minutes each time it is turned on. 

Access Control

Turn your access control smart in a few minutes. Just set an inching duration to release the door magnet for a few seconds and turn the circuit off to close the gate. 

Aquarium Pump

Schedule to turn on your aquarium pump to supplement oxygen and set an inching duration of 30 minutes when oxygen is enough. 

2.Momentary Switch Scenarios 
Garage door

Adding app control to your garage door has never been easier. Just connect your traditional garage door controller with an eWeLink Support switch and set an inching duration of 0.5 seconds to send a pulse to the garage door controller to open and close the garage door.

Supported App version: eWeLink V4.0 or above
