Precautions
Caution
Do not apply a voltage higher than the maximum rated operat-
ing voltage between the lamp terminals, as there is a risk that
the incandescent lamp or LED lamp will be damaged, and the
Pushbutton will be ejected.
When replacing the incandescent lamp, first turn OFF the
power supply, and then wait 10 minutes before performing re-
placement, as the lamp is still hot immediately after the power
is turned OFF, so there is a risk of burns.
Refer to the Common Precautions for Pushbutton Switches on
page 14.
Correct Use
Mounting
To prevent electric shock or a fire, always make sure that the power
is turned OFF before mounting, removing, or wiring the Switch, or
performing maintenance.
Do not tighten the mounting ring excessively using pliers or a similar
tool. Excessive tightening may damage the mounting ring. (Tighten-
ing torque: 0.20 to 0.39 N
m)
Wiring
When wiring, use wires of a size appropriate for the applied voltage
and carry current. Perform soldering correctly under the conditions
given below. Using the Switch with the wires soldered incorrectly
may cause the terminals to become abnormally hot and cause a fire.
1. Hand soldering: At 30 W within 5 seconds.
2. Dip soldering: At 240
°C within 3 seconds.
Wait for one minute after soldering before exerting any external
force on the solder.
Use a non-corrosive rosin liquid for the flux.
Perform wiring so that the wire sheaths do not come into contact
with the Switch. If this is unavoidable, use wires that can withstand
temperatures of 100
°C min.
After wiring to the Switch has been completed, ensure an appropri-
ate insulation distance.
Operating Environment
Do not use in locations that are subject to dust, oil, or metal filings as
these may penetrate the interior of the Switch and cause malfunc-
tion.
Using Microloads
Using a standard load switch for opening and closing a microload
circuit may cause wear on the contacts. Use the switch within the
operating range. (Refer to the diagram below.) Even when using mi-
croload models within the operating range shown below, if inrush
current occurs when the contact is opened or closed, it may cause
the contact surface to become rough, and so decrease life expec-
tancy. Therefore, insert a contact protection circuit where neces-
sary. 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 10–4/times indicates that the estimated malfunction rate is less
than 1/2,000,000 with a reliability level of 60%.
