IR series
Sealed momentary pushbutton switches - bushing Ø 16
Distinctive features
The IR series is a range of sealed momentary pushbutton switches with dia. 16 mm bushing. This
series is divided into 2 families : standard models and microswitch technology models.
Common features
• Sealed to IP67
• Illuminated or non-illuminated
• Tactile feedback
• Square or round actuator
• Wide choice of bezel and actuator colours
• Wide choice of illumination colours
Standard versions
• Numerous terminal options :
solder, wire lead, straight PC, quick-
connect, screw
• Screw versions withstanding up to 4A
• Electrical function : NO (2 terminals)
Microswitch versions
• Withstanding up to 5A
• Two electrical functions :
NC+NO (3 terminals)
NC/NO combined (4 terminals)
Optional marking
Actuator marking is available on request
for models with flat round actuator.
Integrated resistor
On wire lead illuminated versions, the LED
resistor can be integrated in the product by
APEM. On request.
