Contact blocks Series S-E - WESTEC

Contact blocks Series S-E - WESTEC are auxiliary switching devices designed for integration into modular control units, pushbuttons, and selector switches. These blocks feature a robust mechanical construction with self-cleaning silver contacts, ensuring reliable low-voltage switching for control circuits. Available in normally open (NO), normally closed (NC), and changeover configurations, they support rated operational currents up to 10 A at 400 V AC and 250 V DC, with a mechanical endurance exceeding 1 million operations. The compact design allows for snap-on mounting on standard 22 mm or 30 mm actuators, making them ideal for industrial control panels.

These contact blocks are widely deployed in industrial automation, machine building, and process control environments. They are commonly found in control stations, operator panels, and electrical enclosures for machinery, conveyor systems, and packaging equipment. Their modular nature facilitates easy replacement and customization in demanding sectors such as automotive manufacturing, material handling, and energy distribution.

Key subcategories include standard contact blocks, illuminated contact blocks, and low-current versions for electronic circuits. The main article codes typically follow the pattern "S-E-XX", where "XX" denotes the contact configuration (e.g., "S-E-NO" for normally open, "S-E-NC" for normally closed). Additional variants include blocks with integrated LED indicators for status visualization. These components are essential for building complete pushbutton stations and selector switch assemblies.
