With the rapid development of science and technology, voice-activated switches have entered millions of homes, providing people with great convenience at night. For voice-activated switches, many people want to understand its characteristics and installation procedures. The following Xiaobian gives you a brief introduction to this aspect. I hope to help you! 
What are the characteristics of voice-activated switches ?
1, sound start-up
As long as a certain sound is generated by hand or other means (such as whistling, shouting, etc.) near the switch, the voice switch will immediately turn on the light and be handy.
2, delay from off
Once the switch is turned on, the switch will be automatically turned off after a delay of several tens of seconds. This can reduce the unnecessary waste of electrical energy and is convenient and practical.
3, delay appliance life
The voice-activated switch can control the circuit using electronic components and contactless contacts to eliminate wave currents and sparks.
4, energy saving and environmental protection
The voice-activated switch is an automatic lighting switch that integrates acoustics, optics and time delay technology. It is widely used in corridors, building corridors, factories, gardens and other places. It is a modern and ideal new green lighting switch, and extends the service life of the lamp. Can save electricity.
What are the voice-activated switch installation steps?
1. The original switch is dismantled: The original switch and attached device are to be dismantled, and the installation and wiring conditions should be carefully observed before disassembly to avoid the switch being damaged due to blind disassembly.
2, clean up:
(1) Remove the debris from the junction box with a brush, and clean the debris on the thread head.
(2) If the inner surface of the metal junction box is rusted, the anti-rust paint should be promptly brushed after rust removal. The debris in the box should be cleaned.
3, wiring:
(1) The contact is reliable and the operation is flexible.
(2) The wire insulation resistance test is qualified and there is an insulation resistance test record.
4, installation:
(1) Leave the wire removed from the box for the length of the repair, cut the insulation, and take care not to injure the wire core.
(2) Coil the wire in the clockwise direction on the corresponding terminal of the switch, then tighten the head.
(3) If it is a single core wire, insert the wire core directly into the wire hole. When the hole diameter is greater than 2 times the wire diameter, it should be bent back into the wire hole and then pressed with the top wire. Note that the wire core should not be exposed.
5, power running:
(1) After the voice-activated switches have been installed, the insulation test of each branch shall be performed first, and check whether there is any open circuit, short circuit and insulation damage in the switch assembly.
(2) After passing the insulation test, it shall be transmitted step by step in sections.
Edit Summary: The above is the switch which features the voice, the voice switch installation steps which have relevant knowledge introduction, I hope we can learn from. Voice-activated switches are used more often in life, so information about them can be introduced to you and you can use them in the future.
