Free Datasheet http://www.Datasheet4U.com
VS01...All-molded DC-only compact switch
These switches concentrate NKK’s advanced contact technology and reliable design to achieve HVDC cutoff!
(Patent pending, design registered)
Compact body size
The body size is compact enough to mount in a 19-inch rack, but it is rated for DC420V, 15A (high-capacity type).
Designed With Care to Prevent Misoperation
The slide control was designed to prevent misoperation, with a barrier structure to stop unintentional operation.
Safe Insulation Structure
The insulation structure, compliant with EN61058-1 Class II, ensures safety.
Open/close durability
This unique structure achieves electrical open/close durability for over 10,000 cycles.
Insulation Cover Provided as Standard
We provide the insulation cover as a standard accessory, to guard against electric shock.
We use a unique structure to safely cut off a powerful arc
The internal mechanism uses insulation plates that can safely cut off a powerful DC arc. The mechanism opens and closes the contact at a constant speed, regardless of the operation speed. It safely cuts off a DC arc. The structure does not use magnets,
Snap-in Mounting
Panel mounting is by snapping into place, cutting the amount of work required.
Arc
so it is not prone to influence from the surroundings.
Our proprietary structure
Occurrence of arc
Occurrence of strong arc
Arc is cut by our proprietary structure (Patent Pending)
Terminals are open safely.

Precautions
Panel Cutting ・ Behind the panel, cut area should be squared. If front of panel is painted, do not allow any paint to collect in corners of cutout to prevent level mounting. U se within the rated voltage and current. Use outside the ・ ratings risks short circuits, fire, etc. This product is for use with DC only. It cannot be used with AC. ・ Be sure to use the correct terminal polarity. The terminal face ・ on the bottom of the body case of this product is marked with polarity. Wiring with the wiring terminal polarity will drastically shorten the electric life (to around 1,000). The open/close frequency should not exceed 15 times per ・ minute (operate so that there is an interval of at least 4s after each operation). Continuous open/close operation at high voltage and current could potentially make it impossible to switch off, leading to a major accident. This product should be used with crimp terminals attached by ・ screws. If it is used with the terminals directly soldered, there is the risk of abnormal heating inside this product, leading to fire etc. When operating the switch, turn the knob all the way to the ・ end. Do not.
