Mr. Monotaro, I am always indebted. Although we use it in our tank truck, it has been operating normally without failure even after two years from purchase. I think this product can be recommended with confidence.
Usually I used Kasuga Electric's push button switch for power, this time I bought a strong rainproof and explanation. Let me just say one thing. Please describe the type of switch. Momentary or alternate. I purchased it by mistake and it does not become usable
