Wiring
Operating Environment
Using Microloads
• Always make sure that the power is turned OFF before mounting,
• For wiring, use a wire size that is appropriate for the applied voltage
• Use non-corrosive liquid rosin as the flux.
• If screw-tightened terminals are used, hold the Socket Unit Set or
• Make sure that the insulating sheath of the wires does not come in
• After wiring the Switch, make sure that there is a suitable isolation
• Do not use in locations that are subject to dust, oil, or metal fillings,
• Using a standard load switch when a microload circuit is opened or
removing, or wiring the Switch, or performing maintenance. Electric
shock or fire may occur.
and the supplied current. Be sure to perform soldering according to
the following conditions. Using the Switch with incomplete soldering
may result in errors and heat, which may cause fire.
Wait for one minute after soldering before exerting any external
force on the solder.
Socket Unit and install the lead wiring applying a torque of less than
0.98 N·m to the Socket Unit. Applying a torque of more than 0.98
N·m may result in damage. The tightening torque is 0.59 to 0.78

sheath of the wires coming in contact with the Unit, use wire with a
minimum heat resistance of 100°C.

because these may penetrate the interior the Switch and cause
malfunction.
closed may cause wear on the contacts. Use the switch within the
operating range. (Refer to the diagram below.) Even when using
microload models within the operating range shown below, if inrush
current occurs when the contacts are opened or closed, it may
cause the contact surface to become rough, and so decrease life
expectancy. Therefore, insert a contact protection circuit where
necessary.
The minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability
level of 60% (λ 60) (conforming to JIS C5003).
The equation λ 60 = 0.5 x 10
malfunction rate is less than 1/2,000,000 with a reliability level of
60%.
