2. For the terminals, the crimping type is employed and

the epoxy sealing is applied to prevent ꢀux entry.

3. Adoption of the wiping mechanism for the contacting

area to ensure contacting stability and reliability.

■Handling Precautions

1. Soldering Speciꢀcations

2. Mounting of Accessories

Manual Soldering

Mounting of accessories should be done after soldering

and ꢀux cleaning.

Device: Soldering iron

380℃, Max.; 3 seconds, Max.

3. Ambient Conditions

Do not use the switches under the environment where the

silver plating is subjected to contact failures by sulfuric gas,

ammonia gas or other corrosive gases.

Under the environment where dust and dirt exist, use

waterproof type switches.
