WEG CSW Push Buttons & Pilot Devices
Modular 22 mm & 30 mm operators built for configurable control stations.
CSW modular operators deliver tool-free mounting, LED illumination, and a complete accessory ecosystem so you can engineer reliable operator stations in any environment. Combine plastic or metal bezels with stackable contact blocks, keyed selectors, and emergency-stop operators to standardize every panel door across your fleet.
Operator Platforms
Flush, extended, mushroom, selector, and key-operated versions with quarter-turn latching bezels.
Die-cast metal bodies, positive-guided contacts, and heavy-duty keyed selectors for harsh duty.
40/60 mm actuators with twist- or key-reset, positive-opening contacts, and optional protective shrouds.
Mechanical Ratings
Up to 3 million cycles for maintained operators; 1 million for E-stop duty.
IP66/IP69K, UL Type 4X/12 with appropriate sealing accessories.
-25 °C to +70 °C standard, optional low-temperature kits available.
Electrical Ratings
600 V UL listed, 10 A AC-15/600 V, bifurcated gold contacts for low-level control.
Field-replaceable LED modules 12–240 VAC/DC with resistor networks for AC/DC compatibility.
Positive-opening blocks meet EN 60947-5-5 and ISO 13850 for Category 4 circuits.
Panel Integration
- Snap-on contact blocks stack up to six deep with late-make/early-break options.
- Pluggable terminals simplify harnessing and allow pre-wired operator stations.
- Legend plates, protective boots, and padlock attachments maintain labeling compliance.
- Modular signaling towers share bases, LED modules, and audible elements.
Design Advantages for OEM & MRO Teams
Tool-Free Mounting
Quarter-turn rings secure operators in seconds while maintaining high pull-out resistance for UL Type 4X panels.
Flexible Contact Stacks
Mix NO/NC, early-make, and late-break blocks with direct-mount accessories to build complex circuits in a compact footprint.
Brilliant Illumination
High-intensity LED modules with integrated resistors maintain uniform brightness across wide voltage ranges.
Complete Accessories
Assemble keyed selectors, potentiometers, joysticks, guards, legend plates, and pre-drilled enclosures from a single platform.
