Abstract
The invention provides a button switch with a power-off protection module. The button switch with the power-off protection module comprises a button switch body. The power-off protection module is integrated in the button switch body. Two-phase power transmission lines are connected with a switch contact and the power-off protection module respectively. The power-off protection module is connected with the switch contact in parallel through a signal spring. The signal spring conducts detection, compares the input voltage with the output voltage of the switch contact to judge whether a voltage passes through the switch contact and sends a signal to the power-off protection module. If the power-off protection module receives the signal which shows that the voltage passes through the switch contact, the power-off protection module maintains voltage transmission. If the power-off protection module receives the signal which shows that no voltage passes through the switch contact, the power-off protection module cuts off voltage transmission. By the adoption of the button switch with the power-off protection module, on the condition of not changing the shape and dimensions of an original button switch, the power-off protection module is integrated in the button switch body to achieve power-off protection control.
