This series pushbuttons consist of two main systems:one is screw-set unit,which forms
the operating device,another is the basic unit,which acts as the contact device.All the
constructional connections adopt the advanced international technologies that are intergrated
snap-fastening and self-locking modes without any clamping units,so it is highly
dependable mounting position of pushbuttons and prevent them from becoming loose.
The basic unit of this series pushbuttons have 1 NO and 1 NC or 2 NO and 2 NC contacts
with self-cleaning system.It belongs to single break momentary switches.Both the contact
head and contact piece are gold-plated to ensure a reliable contact and stable electrical performance.
All kinds of logoes and indicationes can be configured up to customers' request.
