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
■ Cautions
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;
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.

Current (mA)
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
Use of soldering iron for normal soldering is acceptable.
Soldering hook holes version available.
Soldering terminal types 1 and 2 are met.
