Detailed Description

As shown in fig. 2, the present invention provides a remote control switch device, which includes a communication terminal (21), a power amplifier module (22), a trigger relay module (23), delay relay modules (24) (25), key switches (26) (27), and controlled switches (28) (29).

The communication terminal (21) in the device is a device which can receive telephone calls and short messages or can run instant communication software such as QQ and WeChat and can send out prompt tones.

In some embodiments, the communication terminal in the device can access the internet through a mobile data network of a mobile phone or through WIFI.

In some embodiments, the power amplifier module (22) is used for amplifying the audio signal output by the earphone hole of the communication terminal and transmitting the audio signal to the signal end of the trigger relay module (23) through a wire.

In some embodiments, the trip relay module (23) is a relay module having a signal input and an on or off control. And the signal end is used for outputting the trigger signal to the delay relay modules (24) and (25) through wired connection after receiving the trigger signal output by the power amplifier module (22).
