としては「ネオラ/ブ」が広く用いられている。Among the electrical equipment generally available on the market, the working voltage percentage of this type of electromagnetic switch is AC200V (
There are about 70 units of D items, and about 20 units of ACloovO items.
It is said to be regrettable. Each electromagnetic switch is equipped with a pilot lamp, or operation display device, to indicate that it is in operation, and ``Neola/Bu'' is widely used as the light source. .

そして在庫しなければならない欠点がある。However, as mentioned above, the working voltage is AC200
In the case of V, the operating voltage is high and the operation display is extremely bright, but the life of the neon lamp is shortened, and when the operating voltage is AClooV, the life of the neon lamp is long, but the operation display is low in brightness and dark. Therefore, we have manufactured many electrical devices such as electromagnetic switches equipped with operation display devices on the operating voltage side.
And there is the drawback of having to stock up.

The aim is to provide equipment.
