A membrane key complements now the stainless steel actuators of the RONTRON-R-JUWEL-VA series by Schlegel. Just like its “relatives“, the membrane key distinguishes by an elegant appearance due to its round shape and low profile, and it is mainly used in areas setting high standards in quality and design. As it complies with the degree of protection IP69K, it is suitable for applications in particularly demanding environments, e.g. the food processing industry. Due to its labelling and illuminating options, the membrane key provides great flexibility in the control panel design.
