[0021] After connecting the product of the present embodiment to the equipment circuit, it will first detect and determine whether the signal input end of the equipment is high or low level, so as to determine whether the NPN signal or PNP signal is required for the signal input of the equipment. If the signal input end of the equipment is high level, the sensor switch will act as an NPN output signal switch. If the signal input end of the equipment is low level, the sensor switch will act as a PNP output signal switch. After obtaining the signal input mode required by the equipment, the switch will have different color action indicator lights when outputting NPN signal or PNP signal to tell the user what signal the equipment needs at this time, so that the user can more intuitively understand the current equipment signal input condition. For example, the sensor switch of the present embodiment detects that the signal input end of the equipment is high level. After the sensing signal passes through the sensor switch, the switch outputs an NPN (low level) effective signal, and at the same time, the red signal output indicator light on the sensor switch is turned on. After the equipment receives the sensor switch signal, the next action is executed. If the green indicator light on the sensor switch is turned on, it represents that the PNP (high level) signal is output. In this way, non-professionals can know whether the NPN type or PNP type sensor switch is required by the current equipment.
