Safety Precautions

Handling

• The molded components of the Switch use polyacetal resin and

ABS resin. It is recommended that alcohol is used to wipe off dirt

and smudges from the molded components. Take care to prevent

the alcohol from getting inside.

• A7P Thumbwheel Switches are dust-proof, but they are not drip-

proof. Do not use them in areas subject to water or oil exposure.

• Do not allow solder flux or alcohol to enter the Switch.

• Do not push the (+) and (-) operating push-buttons at the same time.

• To separate the Switches, use a flat-blade screwdriver as shown in the

following figure to release the hooks on the top and bottom and then

separate the Switches. Be careful not to bend the hooks.
