An X-ray hand switch is a handheld control device. Typically, it has 2 gears, though 1-gear (e.g., for dental X-ray units) and 3-gear versions also exist.
For the 2-gear hand switch, the graded switch activates when the button is pressed and deactivates when released. Pressing the button to the first step (Gear I) fully engages it, and Gear I remains active. Most 2-gear hand switches are also equipped with a fixed bracket.
Wiring Testing Method
-
Gear I (READY) Testing:
-
Keep the X-ray hand switch in Gear I (READY) state. Set a multimeter to diode test mode (it will beep to indicate a valid connection). Use the multimeter’s red probe to touch Pin 1 of the RJ plug, then use the black probe to test Pins 2, 3, and 4 in sequence. Next, place the red probe on Pin 2 and test Pins 3 and 4 with the black probe, repeating this process for all pin combinations. Record the plug’s pin numbers to confirm the wiring pattern.
-
Gear II (X-RAY) Testing:
-
The wiring test method for Gear II (X-RAY) is identical to that of Gear I (READY).
