🔧 Product Description

The Olympus TH4-HS (SKU: TH4-HS) is the OEM hand switch designed specifically for use with the Olympus TH4 12V 100W transmitted light power supply, commonly found on Olympus BX, IX, and CX series microscopes. Rather than adjusting illumination intensity at the power supply unit itself, the TH4-HS allows the operator to control brightness from a convenient handheld unit positioned at the stage — a practical advantage during live imaging, documentation, or any workflow where frequent brightness adjustments are needed. As a genuine Olympus accessory, it ensures full compatibility and reliable performance with TH4-equipped systems.
