What Is the Orthoscan Laser Switch Assembly (920-0077)?
Product: Orthoscan Laser Switch Assembly
Part Number: 920-0077
The Orthoscan Laser Switch Assembly (920-0077) is the operator-facing switch and wiring harness that activates the laser aiming beam on Orthoscan Mini C-Arms. When pressed, this switch energizes the laser diode assembly (920-0080), projecting the visible red targeting crosshair onto the patient to center the fluoroscopy field before exposure. The switch assembly spans the full Orthoscan product line — from the earliest UC platform through the current TAU 1512, 1515, and 2020 — making it one of the most broadly compatible control parts in the Orthoscan catalog. A failed switch typically presents as a laser that cannot be activated from the c-arm head controls, even when the laser diode itself is functional. Because diagnosing a laser activation failure requires isolating whether the fault is in the switch assembly or the diode, both components should be inspected before ordering.

What does the laser switch assembly do on an Orthoscan mini C-arm?+
The laser switch assembly is the control that the operator presses on the c-arm head to activate the laser aiming beam. When engaged, it sends the activation signal to the laser diode assembly (
920-0080), which projects a visible red crosshair onto the patient to indicate the center of the fluoroscopy field before x-ray exposure begins.
How do I know if the problem is the switch or the laser diode?+
If the laser does not activate at all when the switch is pressed, either the switch assembly or the diode may be at fault. A qualified biomedical engineer can isolate the fault by testing continuity through the switch and checking whether the diode receives its activation signal. Call (800) 643-2998 and our team can help you triage before you order either part.
What symptoms indicate a failed laser switch assembly?+
The most common symptom is complete inability to activate the laser from the c-arm head controls even though the laser diode itself may be functional. Intermittent laser activation — where the beam flickers or only activates with specific pressure on the switch — also points to a failing switch mechanism or connector.
What does sold on exchange mean?+
Exchange means you return your defective core unit when you receive the replacement. This helps keep costs down and ensures defective units are properly refurbished. Our team will provide return instructions with your order.
How quickly can I get this part shipped?+
Same-day shipping is available on in-stock parts when ordered before 5PM EST. Call (800) 643-2998 to confirm availability and arrange shipping.
