What is the contact gap of a basic switch?

Answer
The contact gaps for Omron’s basic switches are as follows:
V size: F gap / 1 mm / Standard value
S size: G gap / 0.5 mm / We also have F gap limited to NC specifications.
J size: H gap / 0.25 mm
Explanation
The contact gap of a basic switch is determined largely based on its size. A larger contact gap is advantageous for withstanding voltage and DC cutoff, while a smaller contact gap is advantageous for repeatability of detection and electrical durability. In recent years, demand for a large contact gap has been increasing to withstand voltage requirements and power supply interruptions (primary and secondary), even in small sizes. A 1 mm gap variation has also been added to SS models.

Q
What is the withstand voltage of a basic switch?
- A
The withstand voltage of a basic switch indicates the high voltage that does not break the insulation (1) between the same polarity terminals, (2) between current-carrying metal parts and grounds, and (3) between terminals and non-current-carrying metal parts.

Q
How long does a basic switch last?
- A
Basic switches have electrical life (electrical durability) and mechanical life (mechanical durability).
-
Q
How do I open and close DC using a basic switch?
- A
In direct current switching, the arc (spark generated between the contacts upon switching) lasts longer, causing more severe contact wear compared to alternating current. When cutting off a DC circuit, please select a switch with a DC rating and use it according to the rating.
