Microprecision Electronics SA Extends and Improves MP500 Subminiature Switch Series, Adding MP550 Model, UL and ENEC Certification
MP500 Subminiature Microswitches
Vouvry — Switzerland, November 14, 2011— Microprecision Electronics SA, extended its IP67-rated MP500 subminiature switch line by adding the new MP550 model, which is rated at IP40 for applications that do not require a high degree of protection. In addition to extending the line, the MP500 switch family is now certified under UL and ENEC for up to 5A/250 VAC. This new certification is encompassed under the new harmonized standard UL 61058-1 for appliance switches, which replaces the UL 1054.
For low-current switching applications in humid environments, gold contacts are available to protect against contact oxidation. The switch is available in a cable version, but can also be supplied with PCB or solder pins. In its standard configuration, the switch uses a PVC cable, but other cable or wires can be used upon request as custom solutions.
Additionally, the mechanical characteristics have been optimized for precise and fast switching with a low differential travel of less than 0.05 mm. The switch also supports a large temperature range of -40° C/ +105° C.
Also available in the standard version are straight levers, as well as simulated roller and roller levers. Other custom levers can be designed and manufactured upon request—even in small quantities.
