WEG’s new modular CSW command and signalling devices boost flexibility

Latest from WEG are new CSW series command and signalling devices with new
pushbuttons and contact blocks to help users reduce installation time and
costs by up to 66 per cent.

Designed to increase flexibility and simplify stock management, the
individual contact blocks can be easily combined to meet specific
requirements and assembled without tools. Additionally, the new pushbuttons
have an IP66 / NEMA 4X rating, which means they provide a reliable solution
in harsh environments.

“The modular CSW series maximises flexibility for machine and plant
engineers, meeting their need for cost-effective and convenient solutions
with high reliability and long service life,” says Zoltan Schaaf, ,manager,
low-voltage switchgear, WEG Germany. “Thanks to our new pushbuttons and
contact blocks, together with surface-mount housing and flexible
combinations, the CSW series is a great fit for a wide range of industrial

There are new dual and triple pushbuttons in the range, which combine the
functions of two or three individual buttons into one single button of
diameter 22.5 mm. This reduces installation time significantly, enabling the
user to save associated costs. The buttons have a mechanical lifespan of
millions of operations, so users can be confident they are reliable over a
long service life and machine builders can specify flush or protruding stop
buttons to best suit their needs. The advanced sealing system gives the high
IP66 ingress protection rating meaning they are dust tight and protected
against powerful jets of water, for excellent operation in in outdoor

The modular contact blocks are click-mounted for fast and easy assembly.
Fitting in the surface-mount housing and mating with the panel-front
pushbuttons is also toolless. Additionally, silver alloy contacts ensure
long service life and high contact sensitivity, with the contact systems
designed to be self-cleaning. This means that contact resistance is
minimised and contact reliability optimised and even low-voltage and
low-current signals (5 mA at 17 V) can be transmitted reliably. In addition,
all normally closed contact blocks fulfil IEC/EN 60947-5-1 functional safety
requirements for forcibly guided contacts.

The CSW command and signalling devices are designed, tested and manufactured
according to the IEC/EN 60947-5 (DIN VDE 0660). All devices are made using
flame-resistant, self-extinguishing, impact-resistant and UV-protected
plastic (UL Yellow Book listed) and are UL/CSA approved for use worldwide,
says the company.
