Continuous Soldering Time: 5 second Max. ■ Precautions in Handling 1. Care should be exercised so that flux from the top surface of the printed circuit board does not adhere to the switch. 2. Do not wash the switch. ■ Operating precautions 1. Do not actuate the switch with excessive force. 2. Discontinue force after the switch has been actuated so as to avoid deformation of the components of the switch. Deformation of the components may cause the switch to malfunction. 3. Align the plunger with the switch to insure proper operation. ■ Notes on storage conditions Avoid the following as exposure may affect the performance and/or the soldering of the switch: 1. Temperature of -10 to +40℃ & 85% humidity. 2. Exposure to corrosive gas. 3. Storage over 6 months 4. Exposure to direct sunlight. 5. Storage conditions should prevent heavy impact or loading. 6. After opening the package, unused switches must be repackaged in a moisture-proof and airtight environment.
