Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 and figure 2 As shown, the present invention mainly includes the relay to be controlled in the scan switch, the PCB circuit board 4 , the FPC flexible circuit board 3 , the rear panel 6 and the low thermal potential terminal post 5 . Such as image 3 As shown, a PCB circuit board 4 and a rear panel 6 are respectively installed on both sides of the wave-shaped FPC flexible circuit board 3, and an FPC flexible circuit board 3 is installed between the PCB circuit board 4 and the rear panel 6, and the PCB circuit board 4 is installed with a relay 1, and the two signal pins 8 of the relay 1 are connected to the FPC flexible circuit board 3 through the through slot 7 of the corresponding PCB control circuit board 4, so that the signal pins can pass through it. Solder joint 2 is produced by direct welding between ...
