Cautions For Use

AV4 (FU) Switches Cautions For Use

1.Fastening of the switch body

1.In fastening the switch body, use the M1.4 screw (3 types ... screw head diameter from 2.4 dia. to 2.6 dia.), with tightening torque of not more than 0.098 N·m.
2.In setting the movement after operation, the over-travel should be set within the range of the minimum OT value. Please set up so that a operation object does not apply force to the switch body.

2.Environment

Avoid using and storing these switches in a location where they will be exposed to corrosive gases, silicon, or high dust levels, all of which can have an adverse effect on the contacts.

3.Soldering

1.Manual soldering should be accomplished within 5 seconds with max. 320°C iron. Care should be taken not to apply force to the terminals during soldering.
2.Terminal portion must not be moved within 1 minute after soldering. Also no tensile strength of lead wires should be applied to the terminals.
3.When using the angle terminal type, insert an insulation separator between the switch body and the P/C board (Insulation separator 0.2 to 0.4mm thick) to prevent the soldering flux from flowing under the P/C board.
