Smallest Rotary Switch for Harsh Environments

May 29, 2013 02:00 PM

Grayhill, Inc. today introduced a small and sealed rotary switch, the 77 Series. This compact rotary switch requires less than a quarter inch behind panel, making it ideal for handheld devices. Further, its MIL-rated resistance to moisture, sand and dust indicates that it is suitable for harsh, outdoor environments.

Military handheld radios, night vision goggles and laser aiming devices all require rotary switches to select settings. Because the typical soldier carries more than one of these devices, size is an important consideration. The 77 Series rotary switch will fit on almost any device. Its diameter is only 0.5 inches and it requires just 0.18 inches of clearance; the smallest rotary available with this level of seal.

Compact, sealed 77 Series rotary switchThese devices are carried through some of the harshest environments from driving rain to swirling dust storms. Because of this, the environmental seal is almost more important than the size. An unsealed switch would quickly lead to a malfunctioning device. Grayhill’s 77 Series rotary switches have endured rigorous testing to confirm they meet military specified standards for resistance to moisture, salt spray, underwater immersion, sand and dust.

The 77 Series is available with or without a process seal or a shaft and panel seal. It can switch up to 10 positions in single pole configuration or up to 5 positions in a double pole configuration. The 77 Series can be ordered with continuous rotation or a fixed stop. The contacts are non-shorting, wiping contacts.

As your product development partner, Grayhill can customize the 77 Series to meet unique electrical or environmental requirements. Modifications can be made to achieve different cycles of operation, currents, temperature ranges or atmospheric pressure conditions.

For more information, see the 77 Series datasheet.
