LED and Incandescent Pushbutton Switches and Accessories

Aerospace Optics is the exclusive manufacturer of the VIVISUN brand of lighted pushbutton switches and programmable displays. VIVISUN combines reliability, MIL-PRF-22885 quality and superior performance in a sunlight-readable, lighted pushbutton switch or indicator. VIVISUN products meet a number of military, environmental and electrical specifications.

VIVISUN LED switches are an ideal choice wherever machine-man interface lighting is critical. They are easy to install and highly reliable, with virtually zero maintenance required. VIVISUN switches also feature a fault-tolerant circuit design with low power consumption and low heat. They are manufactured under a proven, quality assurance system that ensures defect-free products, outstanding customer service and prompt delivery.


The VIVISUN LOGIC SERIES is the first LED pushbutton switch based on an integrated logic circuit. The LOGIC SERIES is an electromechanical switch with multiple operational modes that are controlled by discrete inputs. Its integrated, solid-state circuitry allows different poles in the same switch to function as momentary or alternate action, without external relays or holding coils, which simplifies and improves operator interface. The LOGIC SERIES has the ability to automatically reset to a safe mode when power is cycled and can be locally or remotely set or canceled. It also interfaces with external sensors to allow for conditional switching or lockout modes.

Standard ¾-inch, square pushbutton switch

The VIVISUN LED is a MIL-PRF-22885/108 (MIS-S-22885/108) lighted pushbutton switch featuring sunlight readability, NVIS compliance and voltage-controlled dimming. It is a standard ¾-inch, square switch that operates off existing cockpit power. The solid-state LED technology is designed for an operating range from -40°C to + 71°C. The VIVISUN LED is available in 11 sunlight-readable colors and can be sealed or unsealed in solderless or turret terminations.

1-inch by 1.2-inch, rectangular pushbutton switch

The VIVISUN LR3® is an NVIS-compatible, lighted pushbutton switch. The LR3’s 1-inch by 1.2-inch rectangular configuration provides more display area than the standard LED, making it ideal for master caution and master warning applications. The VIVISUN LR3 features increased character capacity and improved readability with four independent LED quadrants. The LR3 is sunlight readable, has voltage-controlled dimming and is highly reliable — its MTBF is 270,000 hours.

Square, incandescent pushbutton switch

The VIVISUN 95, available in two-pole or four-pole configurations, is a mil-spec qualified, lighted pushbutton switch. The VIVISUN 95 remains readable even in direct sunlight — MIL-PRF-22885/108 (MIL-S-22885/108) — and complies with MIL-STD-3009 and MIL-L-85762A for night vision goggle lighting. VIVISUN 95 incandescent switches have an electrical life of 50,000 cycles minimum, at rated loads of +71°C ambient temperature.

VIVISUN 5000: electro-optical display system

The VIVISUN 5000 is a unique product that combines the industry-leading performance of VIVISUN MIL-PRF-22885 (MIL-S-22885) lighted pushbutton switches with a reconfigurable, programmable LED display. The VIVISUN 5000 provides interactive displays that are NVIS compatible, sunlight readable and ready to interface directly with the host computer. It consists of four programmable multifunction pushbuttons (PMP), one refresh processor unit (RPU) and four cables that connect each PMP to the RPU.

VIVISUN accessories

VIVISUN accessories were designed to complement the quality and superior performance of VIVISUN switches and programmable displays. Accessories include switchguards, which prevent inadvertent switch actuation, and panel plugs, an economical and aesthetic option to filling unused switch positions.
