Stern Switches / STERN Engineering

Stern Switch Distributor Since 1989, Stern has developed and manufactured electronic faucets and flushing devices operated by infra-red sensors which are marketed all over the world. Stern has been offering basic Piezo solutions for several years. Around two years ago, Stern decided to take on the Piezo technology as one of their core competences, investing in developing new and innovative Piezo products and starting in-house production of the Piezo technology. Several reasons have led to the decision to strongly focus on Piezo products and components. On one side, the market for sanitary products has a strong need for controlling water supply electronically, where, currently, water supply is still being controlled mechanically. However, the need for a vandal proof interface and for a cost effective solution still exists. Piezo operated products provide an excellent solution by providing a product interface without moving parts based upon a proven and widely used technology, allowing a very accurate water flow, hygiene flushes and remote control of the water flow by a building control system. Providing a wider freedom of product design is one of the other reasons that Stern started with Piezo production. Piezo controls can be seamlessly integrated into products and panels for high-end residential applications providing a clean and minimalist look for all kinds of applications. The Piezo technology is also more suited for residential applications than many other technologies, where the need for 'non-touch' products is less important than a simple installation and a reliable technology. It is Stern's opinion that Piezo will play a major role in the commercial and residential market for electronic sanitary and switching solutions.

Sterns' wide range of products include electronic wall-and-deck-mounted faucets, touch-free soap dispensers, electronic flush valves for urinals and toilets, electronic shower controls, shower panels and vandal-resistant shower heads. Stern also produces a large variety of components, including infrared sensors, piezo switches and solenoid valves. Sterns product quality has long been endorsed by ISO-9001.

Designed for high traffic/high abuse restroom patterns, Stern products are installed in airports, shopping areas, healthcare centers & hospitals, stadiums, prisons, schools and restaurants. Stern has perfected the balance between form and function and after more than a decade of experience in developing and producing electronic faucets. Stern is an industry leader that offers performance, quality, technology, and innovation.

PIEZO Switches

Stern's Smartswitch Piezo switches line, offers advanced technology in a high finish. Stern switches can be used in outdoor machines like fuel pumps, car wash stations, weighing stations etc, where they are exposed to harsh weather conditions. In applications where there is no need for machine status indication, Stern's non-illuminated range is advisable. Ring or dot illuminated switches, provides an advanced user interface in the form of visual operation-feedback or switch mode indication, and are advisable for more advanced applications.
 
 
PROGRAMABLE PIEZO SWITCHES
The programmable Piezo switches family represents a range of switches operated by touch and featuring various time-delay and automatic activations functions. Based on the basic Piezo switch, the programmable Piezo switch is an integral solution for any practical switch activation market.
The Smartswitch keyboard is a one piece construction, to which individual switching units are added. It is than potted at the back of the panel, and is anodized printed. As a result, it has a perfect seal against water, can withstand harsh weather conditions, and is vandal resistant.
