Suggestion for Application Application in occasions that require vibration functions, adding design of “ON DELAY” is recommended. For great vibration, Optical type products are recommended. 2. Suggestion Contact Rating: 5 mA. 3. For the continued product improvement as one of the company policy, specifications may change or update without notice. The latest information can be obtained through our sales offices. Normally, all products are supplied under our standard conditions. « PRECAUTIONS FOR USE 1. If the products is intended to be used for other endurance equipments requiring higher safety and reliability such as life support system, space and aviations devices, disaster and safety system, it’s necessary to make verification of conformity or contact us for the details before using. 2. Don’t try to clean the switch with a solvent or similar substance after the soldering Prozess. 3. The switch might be damaged if using the water-soluble flux. 4. The switch might be apart if the so ldering condition over specification. 5. Don’t use the switch in the environment with high humidity or other bedewing possibility, as it may cause leaking among the terminals. 6. It might catch fire if the rating exceeds the specifications. Never use the switch beyond the Rating. « PACKAGE Part Number 1.
