Grayhill Introduces Series 77 Small Sealed Rotary Switch

Elle Chrupcala

Designed for rugged environments, the Series 77 meets military standards for shock and vibration, moisture resistance, salt spray, underwater immersion, and sand and dust conditions. It features shaft pushout/pull out rotational stop strength, and axial/transverse loading required for rugged applications.

With a higher rotational torque and stop strength than other switches, the Series 77 gives users more positive response on switch position for no-look operations. Rotational torque can be customized to suit particular applications.

Key advantages include:

· Minimum footprint – 0.5-inch diameter and 0.18-inch behind panel

· Process seal, shaft and panel seal available – Seal withstands 10 meter immers10-meterirements, per MIL-DTL-3786

· High stop strength – 7.5-inch pounds minimum

· Continuous rotation or fixed stop available

· Single deck with 1 (10 positions) or 2 poles (5 positions)

· Both Shorting and Non-shorting, wiping contacts variants

· Up to 25,000 life cycles

Review the Series 77 datasheet for more information on electrical specifications, mechanical and environmental ratings, and material finishes.
