Abstract

The invention discloses an improved system switch comprising a resistor R1, a resistor R2, a resistor R3, a resistor R4, a triode T1, a triode T2, a wireless signaler, an on-off signaler and an on-off circuit. The wireless signaler, the resistor R1, the triode T1, the resistor R3 and triode T2 are sequentially connected in series. The resistor R2 and the triode T1 are connected in parallel. The resistor R4 and the triode T2 are connected in parallel. An emitting electrode E of the triode T2 is connected with the on-off signaler. A collecting electrode C of the triode T2 is connected with the on-off circuit. Due to the structure, an external wireless signal is used as a control signal of the on-off circuit, so that the on-off signaler of a whole system controlled by the on-off circuit is controlled.

Description

technical field [0001] The invention relates to a system switch, in particular to an improved system switch. Background technique [0002] In the field of wireless signals, a system switch is widely used as a common setting, in which the switch circuit is used to directly control the switch signal of the entire system. In the field of wireless communication, different wireless signals are often received, and the existing system switch can only realize the control of the physical circuit but cannot realize the switch control of the wireless signal. When the wireless signal changes, it is transmitted into the system, and the switching circuit in the system will also be adjusted accordingly. In the prior art, no external wireless signal is used as a control signal of a switch circuit, and then the switch circuit is used to control the switch signal of the whole system. That is to say, in order to perform power-on and power-off operations on the system, it is impossible to sen...
