Membrane Switch "Waterproof Type"

basic information

The "Waterproof Type" membrane switch is a membrane switch that can also comply with IP standards and others. To prevent water from entering from the outside, the perimeter of the contact area is surrounded by a highly adhesive waterproof tape, enhancing its waterproof properties. Essentially, it can accommodate any type of membrane switch, including flat, click embossed, and poly dome types. It is mainly used in places where high waterproof performance is required, such as the control units of outdoor radios and payment machines for coin parking, and it has received positive feedback for its high reliability. 【Features】 ■ Can comply with IP standards and others ■ Compatible with any type of membrane switch ■ Mainly used in places requiring high waterproof performance ■ Highly reliable and well-received *For more details, please refer to the PDF document or feel free to contact us.*

  ■Implementation example: Thickness adjustment of waterproof tape: Yes

  ■Implementation Example: Waterproof Tape Thickness Adjustment: None (Adjusted by the casing) Not aligning the thickness of the waterproof tape with the thickness of the switch section can reduce the unit cost of the membrane switch. However, in that case, the waterproof sheet portion will become thinner, so it will be necessary to adjust the thickness using the casing. (→2. No adjustment of waterproof tape thickness)

  <Case Study> Membrane Switch Control Panel for Coin Parking Machine (IP67 Waterproof) This is a case where a membrane switch is used for the control panel of an outdoor flat coin parking machine. Since it is for outdoor use, we have designed a fully waterproof membrane switch to prevent rainwater and other elements from entering and causing electrical malfunctions (IP67 waterproof). There have been no major reports of issues, and we have shipped over 5,000 units to date. Even after more than 15 years since development, we continue to receive regular orders.

  <Case Study> Operation Panel of Digital Pressure Gauge This was produced at the request of a pressure gauge manufacturing company. In pursuit of both environmental resistance and ease of use, it features a waterproof type with high reliability and a click-embossed type that enhances tactile feedback and design. The size of the embossing (emboss diameter) is very small at Φ6, but through careful design, we have achieved a good clicking sensation. Although the development was about 15 years ago, we have not received any reports of defects and have received positive feedback from customers. We continue to receive regular orders to this day.
