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.
