Snap Action Switch SS 101
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
Mount the switch onto a flat surface. Mounting on an uneven surface
may cause deformation of the switch, resulting in faulty operation or
breakage in the housing.
Operating Stroke
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 dis-
tance, otherwise the life expectancy of the switch may be shortened.
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.
Cautions
Handling
Turn OFF the power supply before mounting or removing the switch,
wiring, or performing maintenance for inspection. Failure to do so
may result in electric shock or burning
Terminal Connection
When soldering the lead wire to the terminal, first insert the lead wire
conductor through the terminal hole and then solder.
Make sure that the capacity of the soldering iron is 60 W maximum.
Do not take more than 5 seconds to solder the switch terminal.
Improper soldering involving an excessively high temperature or
excessive soldering time may deteriorate the characteristics of the
switch.
Be sure to apply only the minimum required amount of flux. The
switch may have contact failures if flux intrudes in the interior of the
switch.
Use the following lead wires to connect to the solder terminals;
If the PCB terminal models are soldered in a solder bath, flux will per-
meate inside the switch and cause contact failure. Therefore, manu-
ally solder the PCB terminal.
Wire the quick-connect terminals (#110) with receptacles. Insert the
terminals straight into the receptacles. Do not impose excessive
force on the terminal in the horizontal direction, otherwise the termi-
nal may be deformed or the housing may be damaged.
Insulation Distance
Use a separator between the switch and metal mounting panels, to
ensure proper dielectric characteristics are achieved.
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 1.6 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.
