Mounting
All D3C switches may be panel mounted using M1.6 mounting
screws with plane washers or spring washers to securely mount the
switch. Tighten the screws to a torque of 4.9 to 9.8 x 10

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 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 in the housing.
■
Cautions
Terminal Connection
When soldering the lead wire to the terminals, first bind the lead wire
to the terminal and then apply the 60(Sn):40(Pb) solder to the termi-
nals. Complete soldering within 5s at a soldering iron temperature of
260°C. Soldering at a temperature exceeding 260°C, soldering for
more than 5 s, or repeated soldering will degrade the switch charac-
teristics.
When soldering the lead wire to the PCB terminal, pay careful atten-
tion so that the flux and solder liquid level does not exceed the PCB
level.
It is also recommended that you apply flux guard to the mounting sur-
face of the switch.
Application of Operation Force to the Lever
Apply operation forces to the lever in its operating direction. Applying
operating force to the lever in any other directions will damage the
switch or cause malfunction.

Switch mounting surface

Mounting Plate
Use materials other than ABS or polycarbonate for the mounting
plate. Since grease is used within the switch, cracks may be caused
if grease from the switch comes in contact with such materials.
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;
Voltage
(V)
30
0.16 mA
100 mA
24
Operating range
12
Inoperable
range

0
0.1

1,000
1mA
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.
