The qualification test was carried out using a high-pressure vapor stream at 90 Bar and a temperature of 80°C. The hermetically sealed piezo switches can now be used in areas, which are regularly disinfected or cleaned using high-pressure cleaners. This renders them ideal for use in applications exposed to high levels of dirt and grime such as food processing, commercial cooking and transportation.

Besides the extraordinarily long lifetime of more than 20 million switching cycles, SCHURTER piezo switches also reveal a high level of robustness due to their stainless steel or aluminum housing. The following mounting diameters are available as standard: 16, 19, 22, 24, 27 and 30 mm. Other mounting diameters, materials, colors and shapes are possible, according to individual design requirements.

Point or ring illumination is offered in mounting sizes 22 mm and up. This feature can be used to illuminate the actuating surface in a continuous mode or to display the switch position ON or OFF. Laser lettering is available and done in house to minimize lead times. A broad range of standard legends and symbols are available. Customer-specific inscriptions are also available.

The robust metal switches of the existing MSM product family are now also available with a push-on, push-off latching function. The switch position (ON / OFF) is easy to recognize from the resting position of the actuator. In the OFF state, the actuator position protrudes from the housing; in the ON state, it is depressed into the housing. This provides a user-friendly actuating function and also prevents inadvertent switching, e.g. caused by objects leaning on the switch. The switch is designed with two isolated contacts and may thus be used for single- and two-pole switching solutions. The MSM LA can be used at an operating voltage of 30 VDC up to 250 VAC at a maximum switching current of 12 A. Due to the IP 67 rating the switch is suitable for different fields of application. The switch is available with a mounting diameter of 19 and 22 mm and may be used within a temperature range of -25°C to +85°C. The design of the new MSM LA is the same as that of the existing MSM product line. In addition, the switch is also available with ring illumination. The illumination can be used to display the switch position or may be activated to provide visibility during night-time use. Typical application areas for the switch include industrial automation, the food-processing industry, passenger transportation, medical equipment, measuring devices, info terminals, vending machines and operating units.

Piezo switches from SCHURTER have proved themselves optimal in meeting the demands for extremely long lifetime and for an operating surface that is seal-tight in order to prevent the access of dust and fluids. For the switches with an N.O. switching function, the operating temperature range has been extended to -40°C up to +85°C. This means that the piezo switches can now also be used in outside applications where extreme temperatures and temperature fluctuations may occur. The switches contain no moving parts, have a robust metal housing made of anodized aluminum or stainless steel and are hermetically sealed. The lifetime (lifetime > 20 million switching cycles) is almost unlimited, as barely any material wear or mechanical fatigue arises. The piezo switches are resistant to dirt, sand, dust and water; they can neither freeze nor stick through contact with fluids.

The following mounting diameters are available as standard: 16, 19, 22, 24, 27 and 30 mm. Other mounting diameters, materials, colors and shapes are possible for adapting the switches to specific design requirements. SCHURTER offers the piezo switch with point or ring illumination from a mounting diameter of 22 mm. For devices with night design, the illumination serves to make the actuating surface visible. The ring illumination may also be used for providing optical feedback or for displaying the switch position (ON/OFF). For lettering the actuating surface on our in-house laser-lettering unit, numerous standard lettering possibilities are available. Customer-specific lettering and symbols can also be produced.
