Precautions

Be sure to read the precautions and information common to all Snap Action and Detection Switches, contained in the Technical User’s Guide,

“Snap Action Switches, Technical Information” for correct use.

■ Correct Use

Mounting Direction

Mount lever-operated switches with a maximum operating force of

0.49 N in a direction where the actuator weight will not be applied to

the switch. Since the switch is designed for a small load, its resetting

force is small. Therefore, resetting failure may occur if unnecessary

load is applied to the switch.

Insulation Distance

According to EN61058-1, the minimum insulation thickness for this

switch should be 1.1 mm and minimum clearance distance between

the terminal and mounting plate should be 1.9 mm. If the insulation

distance cannot be provided in the product incorporating the switch,

either use a switch with insulation barrier or use a Separator to

ensure sufficient insulation distance.

Using Microloads

Using a model for ordinary loads to switch microloads may result in

faulty operation. Instead, use the models that are designed for

microloads and that operate in the following range;

However, even when using microload models within the operating

range shown above, if inrush current or inductive voltage spikes

occur when the contact is opened or closed, then contact wear may

increase and so decrease the service life. Therefore, insert a contact

protection circuit where necessary.

Solder Terminal Approval Conditions

■ Cautions

Handling

Be careful not to drop the switch. Doing so may cause damage to the

switch’s internal components because it is designed for a small load.

Use of soldering iron for normal soldering is acceptable.

Soldering hook holes version available.

Soldering terminal types 1 and 2 are met.
