Since the product itself was able to use genuine products, I am very satisfied. Because it is used with opening / closing sensor of the door of the coin laundry dryer, because there are rough customers of use at opening and closing, there are cracks and breakage of the part of the letter L, so we would like to improve strength and materials.
Since the circuit is only NO (a contact), it is hard to use as a door switch. In order to detect abnormality, power supply is always required. I would like you to prepare a switch with NO like Delcatec's MCS-201 or Takigengen's LE-126.
