1. This product does not have a water-proof or drip-proof construction. Prevent ingress of water into the switch. Avoid
using around spilt or flowing. It may cause deterioration of the insulation.
2. Do not apply load on the connecter or lead wire（code）attached to the product. Using the product with load applied
on the connecter/lead wire might cause terminal wobble or contact failures.
3. ON/OFF signal reading（For DC ratings）
Shall be considered when designing circuit and software as follows.
（1）Setting of thresh voltage
A 4V or larger voltage difference between switch ON and OFF is recommended. Thresh voltage should be set to the
center.
（2）ON/OFF signal reading
ON/OFF signal reading intervals should be at a minimum of 50ms with at least 3 repetitions.
4. Connector corresponds to [HLP-03V], manufactured by the J.S.T. Mfg. Co., Ltd.
