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
Turn OFF the power supply before mounting or removing the switch,
wiring the switch, or performing maintenance or inspection. Failure to
do so may result in electric shock or burning.
Mount the switch onto a flat surface. Mounting on an uneven surface
may cause deformation of the switch, resulting in faulty operation or
breakage of the housing.
Allow sufficient insulation distance between terminals, terminal
traces and between terminals and ground.
Operating Stroke Setting
Take particular care in setting the operating stroke for the pin plunger
models. Make sure that the operating stroke is 70% to 100% of the
rated OT distance. Do not operate the actuator exceeding the OT
distance, otherwise the service life of the switch maybe decreased.
Using Microloads
Using a model for ordinary loads to switch microloads may result in
faulty operation. Instead, use the models that are designed for micro-
loads 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, it may increase contact
wear and so decrease the service life. Therefore, insert a contact
protection circuit where necessary.

■ Cautions
Terminal Connection
When soldering a lead wire to the terminal, first insert the lead wire
conductor into the terminal hole and then perform soldering.
Make sure that the capacity of the soldering iron is 30 W maximum
and that the temperature of the soldering tip is approximately 300 °C.
(350 °C maximum.) Complete soldering within 3 s. After soldering,
do not apply external force to the soldered area for about 1 minute.
Using a switch with improper soldering may result in abnormal heat-
ing, possibly resulting in a burn.
Applying the soldering iron for more than 3 s or using an iron that is
rated for more than 30 W may deteriorate the switch characteristics.
When soldering the lead wire to the PCB terminal, pay careful
attention so that the flux and solder liquid level does not exceed the
PCB level.
