Safety Precautions
Refer to Safety Precautions for All Pushbutton Switches .
CAUTION
Do not apply a voltage higher than the maximum
rated operating 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 replacement, as the lamp is still hot
immediately after the power is turned OFF, so there
is a risk of burns.
Precautions for Correct Use
Mounting
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
microload 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
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 ? 6 /times indicates that the estimated
malfunction rate is less than 1/2,000,000 with a reliability level of
60%.
? 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
24
tool. Excessive tightening may damage the mounting ring.

Wait for one minute after soldering before exerting any external

? 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

? After wiring to the Switch has been completed, ensure an
appropriate insulation distance.
