Terminal Arrangement (Bottom View) Do not connect L+ and L- terminals for non-illuminated type Dimensions Pushbutton/Indicator Switch Selector Switch Key Switch A3G A3G Assembly/Disassembly Mounting and Replacing Pushbutton Unit (1) LED/lamp (2) B A Mounting directions for the LED/lamp and screen The OMRON screen doubles the roles in which a pushbutton switch is normally used. The screen may be inserted one of two ways: 1. For operation as a lighted pushbutton switch, fit the LED/lamp so that its guide projection is inserted into the wider opening in the receptacle of the screen. Projection D C (3) (4) E LED/lamp guide Mounting pushbutton unit into switch unit LED/lamp guide Insert the LED/lamp unit into the aperture of the switch with the LED/ lamp unit's guide facing the side of the aperture mouth that does not have the two projections. The pressure applied during insertion should be 2.5kg minimum. Removing the pushbutton unit While holding the recessed portions on both sides, firmly and steadily pull out the top of the screen with your thumb and forefinger. Pulling out the cap with pliers or a similar tool will damage the cap. 2. For operation as an indicator unit, insert the LED/lamp guide projection into the narrower opening in the indicator unit's receptacle. Push the projection of the LED/lamp in the groove of the screen so that the LED/lamp is firmly inserted into the screen of the indicator unit. Recess guide LED/lamp guide Bezel Rotation A3G-S and A3G-K. * Groove of the indicator unit Projection of the LED/lamp Note: The inserting direction of the LED/lamp for the screen is opposite to that for the indicator unit. Pay attention to the mounting direction of the legend plate. Removal directions for the LED/lamp and screen Position the pushbutton unit as shown in (1). Press down on the LED/ lamp angling it in the direction indicated by A. Side B of the LED/lamp disconnects and side C angles away from the screen so that it looks like (2). Turn the LED/lamp in the direction indicated by D. The LED/ lamp projections (two locations) will disconnect from the LED/lamp groove so that it looks like (3). Pull in the E direction and remove the LED/lamp. LED/lamp projections disconnected from their grooves. Twist the knob/key while holding the lock fitting to turn the bezel in 45_ increments. A3G A3G Mounting the Panel Mounting the switch unit on panel Nut mounting * Insert the switch unit from the front of the panel. Place the lock fitting and mounting nut on the terminal side and tighten the mounting nut. For the IP65 type use the rubber seal. Tighten the mounting nut to a torque of 10kg-cm or less. Mounting Contact Block After installing the main unit, mount the contact block from the back of the panel (by snapping into place). Removing the contact block Mounting the contact block * * * * Push contact block into the main unit. * There is a direction to fit. Adjust the white mark of both main unit and contact block so that they align. White marks Precautions Mounting Apply less than 10kg/cm of fastening torque to secure the mounting ring. Wiring When soldering, apply a soldering iron rated at 30W quickly (within 5 secs) or within 3 seconds with a tip temperature of 240_C. Do not apply any external force to the switch for 1 minute after soldering to avoid possible plastic deformation. Use a non-corrosive resin-type flux. Operating environment The protective structure of the IP65 prevents damage due to dust from the front of the panel into the interior or direct spraying of water from any direction. Lamps Applying a voltage greater than the rated voltage to the lamp terminals will damage the LED. As the LED polarity is marked on the back of the switches connect the switches accordingly. The neon lamp normally operates on AC. Others The oil-resistant type (IP65) was evaluated with cutting and cooling oils in general use, and it may not be resistant to special types of oil. When using other oils, be sure to contact your OMRON representative. Operation of selector/key switches Apply less than 5kg-cm of torque when operating selector and key switches. Press the lock button of the contact block and pull to remove. Pull straight, not at an angle.
