Specifications of A22NPS38

• Switch Type: Push Button Switch
• Lead Free Status / Rohs Status: Supplier Unconfirmed

Safety Precautions
Refer to Safety Precautions for All Pushbutton Switches.
Do not apply a voltage between the incandescent
lamp and the terminal that is greater than the rated
voltage. If the incandescent lamp is broken, the
Operation Units may pop out.
Always turn OFF the power and wait for 10 minutes
before replacing the incandescent lamp. If the lamp is replaced
immediately after the power is turned OFF, the remaining heat
may cause burns.

Overall length: 26 mm max.
Power consumption: 2.6 W max.
When DC-specific LEDs are used, wire the Switch so that the X1
terminal is positive.
The LED lights with approx. 0.1 mA or less of micro-current. Take
a countermeasure like adding a resistor to prevent mis-lighting in
parallel to the LED.
The micro-current varies with the machine (leak current or stray

reduction of life expectancy due to extreme wear on the contacts
caused by loads where inrush current occurs when the contact is
opened and closed.
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
estimated malfunction rate is less than 1/2,000,000 operations with
a reliability level of 60%.
