September 26, 2011 - Wilbrecht LEDCO released MP550, an IP67-rated subminiature switch rated at IP40 for applications that do not require a high degree of protection. 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.
