The exposure hand switch is a hand-held switch, with a two-step grading switch. Press the button to turn it on, and release it to turn off. Press the button to the first step to turn on the first step, and all press down to turn on the second step. At this time, the first step is still Keep the connected state, the hand brake is equipped with a fixed bracket.
The detection method of the wiring of the exposure hand switch: the exposure hand switch is kept in the READY state, and the multimeter is used to check the crystal plug 1-4 pins. Method: The multimeter modulates the diode detection file. Use the red and black test pens to connect the multimeter to make a beep. Use the red test pen of the multimeter to place the 1 pin of the crystal head, and use the black test pen to check 2-4 pins in sequence.
Red 1, black 2-4, red 2, black 3-4
And so on
This method can detect the wiring mode of the first gear (READY) of the exposure hand switch (record the number of the plug pin).
The detection method of the second gear (X-RAY) of the exposure hand switch is the same as that of the first gear (READY).
After reading the above content, everyone knows the wiring of the exposure hand switch.
