Subminiature Switches

Wilbrecht LEDCO Inc., a subsidiary of Microprecision Electronics SA, has 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 optimised 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. Wilbrecht LEDCO manufactures LED indicator lights, metal foil resistors and mechanical switches in its QPL-certified South Dakota factory.
