Approvals

Underwriters Laboratories (UL)

Madison Company offers many stock switches with UL 508 approval (file E54633 ).  These and other UL sensor approvals are for specific designs, and some modifications to an approved design may cause the approval to be invalid. If there are critical issues for your application to be considered, please contact Underwriters Laboratories or contact us to determine what course of action would be best.

† Multi Level units are custom made per the customers' specifications. Each number is followed by a four or five-digit suffix. This is approved with a 60 Watt SPST switch only. Additional options allowed with this approval are slosh shields, thermocouples, or RTDs.

Canadian Standards Association (CSA)

CSA tests products for compliance with national and international standards and issues certification marks for qualified products. Certification marks tell potential users that a product has been evaluated by a formal process involving examination, testing, and follow-up inspection and that it complies with applicable standards for safety and performance. CSA is recognized throughout Canada as the premier certification organization for electrical products. For more information on CSA, visit www.csagroup.org.


As with UL approval, CSA certification is design-specific. Therefore, modifications to a certified design may cause the certification to be invalid. Please confer with Madison Company if this certification is crucial for your application.

REACH Compliance

Madison Company knows the obligations inherent to the REACH European regulation and will comply as required. We do not manufacture and/or import preparations or articles containing chemical substances according to REACH.


Madison's Standard level switches and sensors – under codes I0571136, high-level sensor and I0571137, low-level sensor – do not contain SVHCs in concentrations greater than 0.1% by weight.

RoHS & WEEE Compliance

Madison Company wants to assure our customers that all of our products comply with the RoHS and WEEE directives released by the European Union (E.U.).  We are also concerned with keeping our materials free of conflict minerals. You can view our Conflict Mineral Report here for more information.


Beginning July 1, 2006, the Restriction of Hazardous Substances, or RoHS, directive (2011/65/EC) will restrict the level of use of four metals, Hg-Mercury, Pb-Lead, Cr(VI) - Hexavalent Chromium and Cd - Cadmium, in electronic products sold in Europe. Two flame-retardants, PBB - Polybrominated biphenyls and PBDE - Polybrominated diphenyl ethers, will also be restricted in their level of use in these products. The directive on Waste Electrical and Electronic Equipment, or WEEE, which took effect on August 13, 2005, requires all producers, distributors and importers of electrical and electronic equipment to finance "end of life" arrangements, such as collection and recycling, for their products.


One of our goals is to produce products that have minimal impact on the environment; we are making every effort to ensure that the majority of our products do not exceed the hazardous substance limits outlined in the RoHS directive (2011/65/EC). You can also be sure that, should any modifications to the two directives apply to our products, we will make whatever modifications are necessary to maintain our compliance.
