Safety Precautions
Refer to Safety Precautions for all Pushbutton Switches.
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 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.
1. Always make sure that the power is turned OFF before mounting,
removing, or wiring the Switch, or performing maintenance.
Electric shock or fire may occur.
2. After wiring the Switch, make sure that there is a suitable isolation
distance.
Wiring
Solder quickly and correctly at 350°C max and for 3 s or less.
Wait for one minute after soldering before exerting any external
force on the solder.
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
malfunction.
LED (for VDC)
Check the terminal polarity when wiring.
The rated voltage is shown on the plate on the back of the lighting
unit, so be sure to use within the voltage shown.
An LED current-limiting resistor is built in, so there is no need to
mount an external resistor.
Incandescent Lamp
Apply 80% of the rated voltage (operating voltage) to the
incandescent lamp to improve life expectancy and incandescence.
Character Plate (Character Film)
If preparing the character plate separately, use a heat-resistant film
with a thickness of 0.1 to 0.3 mm.
Using Microloads
Using a standard load switch when a microload circuit is opened or
closed may cause contact failure 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 104/time indicates that the
estimated malfunction rate is less than 1/2,000,000 with a reliability
level of 60%.
Others
If the panel is to be finished (e.g., coated), make sure that the panel
meets the specified dimensions after the coating.
