How to find a part number

In the last sixty years MERZ designed and produced several ten thousands of switch variations. If a switch must be replaced, very often after decades, we are pleased to help you. In order to identify and define the proper replacement it is absolutely a must to get the corresponding data of the old switch that needs to be replaced, because of the high number of variations. In the PDF download we want to show you how and where to find the right information. You will help us to answer your request as quickly
as possible by providing the information as described.
