CAUTIONS FOR USE (Common for FS type and FS-T type)

3P CONNECTOR

■ Regarding fastening of switch body

1) To secure the switch, please use an M2.3 small screw on a

flat surface and tighten using a maximum torque of 0.29 N·m.

It is recommended that spring washers be used with the screws

and adhesive be applied to lock the screws to prevent loosening

of the screws.

2) When the operation object is in the free position, force should

not be applied directly to the actuator or pin plunger. Also force

should be applied to the pin plunger from vertical direction to the

switch.

3) In setting the movement after operation, the Overtravel OT

should be set not less than 70% as a standard.

Setting the movement at less than 70% of OT may cause

troubles such as mis-contact and welding due to small contact

force of the switch.

In addition, even if FS type switch actuator is pushed to full limit

of operating position, it does not affect product life. However,

heavy impact and excessive loading should not be applied.

■ Soldering operation

Perform soldering in less than 3 seconds with maximum 350

°C

iron. Care should be taken not to apply force to the terminals

during soldering. We recommend a soldering iron with

temperature adjustment in order to prevent poor quality

soldering.

Please consult us if you intend to use a soldering iron of 60 W or

higher.

■ Environment

Locations where corrosive gases having a bad influence on

contacts are present, and locations where there is an excessive

amount of siliceous or other abrasive dust should be avoided.

■ Regarding connector connections (.110 quick connect

terminals)

For making connections, a dedicated receptacle for .110 quick

connect terminals should be used, and the terminals should be

inserted parallel to the receptacle. Consideration should be

given to mounting so that no tensile load is applied to the lead

wires.

■ In making the switch selection

Consideration should be given to provide for no interference up

to +20% variation of the standard characteristics values.

■ Please select Au-clad contact types when loads are in the

low-level area of 1mA up to 100mA and 5V up to 30V.

See the diagram below for contact specification selection.

■ Reverse insertion prevention

As shown in the diagram, the protrusion on the 3P connector

can only be inserted on the corresponding side of the mounting

frame. That is, using the plunger as a reference, the

subminiature switches can only be inserted in the direction

shown in the diagram: it is not possible to mount it the wrong

way round.
