WEG has further developed the CSW control and signaling device series: On the one hand, new double and triple push-buttons with IP66/NEMA 4X protection have replaced the previous double push-buttons and the entire series now complies with the high protection class. Secondly, up to triple cascadable single contact blocks extend the current single and double contact blocks. The company is also adding contact blocks and LED elements as well as other variants to the pre-configured control and signaling device combinations. The range of double and triple push-buttons now includes, for example, versions with flush-mounted or protruding stop push-buttons. The triple push-buttons combine three functions, which can be flexibly combined according to the application, in one device with a 22 mm diameter hole. The modular individual contact blocks can be easily combined with each other thanks to snap-on fasteners. Installation in the surface-mounted housing and combination with the pushbuttons installed on the front are carried out without tools. A silver alloy ensures a long service life and high sensitivity of the contacts. The contact systems are designed to be self-cleaning. All NC contact blocks fulfill the safety function of positive opening in accordance with IEC/EN 60947-5-1.
