3.Application Notes:
3.1 Suggestions of change-over switch
3.1.1 Select the load current and voltage
Selecting switch, firstly we need to confirm the current and
voltage. Now we have wide current range from 2A to 100A. The common
current values are 20A 25A 32A 64A 75A. And the voltage can be
optional to AC 440V and DC 240V. The price will be different due to
different loads.
3.1.2 Choose gear
For the change-over switch. How many circuits you want to control
and what kind of switching you want to achieved will determine the
contacts & gear. 0-1-2, 0 means non-operation state ( it also
means no changes on any circuits), 1/2 is the first gear and the
second gear respectively. We have 0-7 and it’s optional. More
ordering information plz refer to the specification and discuss
with the sales specialist.
3.1.3 Choose the color and shape of handles
The colors of handles can be Black/White/Red/Yellow/Purple/Grey etc
and the shape can be B /F/ I / L / H/ R/P/GS types. It’s flexible
on appearance. However we suggest to use the common type and common
it means they are the most clean color and most comfortable
handles.
3.1.4 More requirements about products, plz feel free to
communicate with our sales and engineers.
