After mounting the switch unit on a panel, and after tightening the mounting nut, insert the lead wires into the hole on the insulation cover before wiring. Align the insulation cover so that the cylindrical portion of the insulation cover will face the switch unit. This means that the lead wires will be inserted from the barrier side of the insulation cover. After wiring has been completed, slide the insulation cover over the switch unit. PANEL PLUG Select the panel plug which best compliments the design of the mounting panel. The dimensions of the hole cutout for the panel plugs are the same as those of the switch unit. Rectangular Square Round Assembly/Disassembly MOUNTING AND REPLACING THE PUSHBUTTON UNIT Mounting directions of the LED/lamp and pushbutton unit The Omron pushbutton unit doubles the roles in which a pushbutton switch is normally used. The pushbutton unit 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 pushbutton unit. 14 (2) For operation as an indicator unit: Insert the LED/lamp guide into the narrower opening in the indicator's receptacle. A3B A3B REMOVING THE PUSHBUTTON UNIT With your thumb and forefinger, while holding the recessed portions on both sides, firmly and steadily pull out the top of the pushbutton unit. Pulling out the cap with pliers or a similar tool will damage the cap. Mounting NUT MOUNTING * Insert the switch unit from the front of the panel (a rubber seal is provided for the IP65 type only) and tighten the mounting nut inserted from the rear of the panel. * Since a projection exists on the rear portion of the switch unit, if the mounting nut cannot be fitted into position, turn the nut slightly. * The tightening torque of the mounting nut should be less than 5kg-cm. * Solder the terminals after mounting the nut. Otherwise, the terminals when thickened by solder, may prevent the nut from being screwed down onto the switch unit. SNAP-IN MOUNTING * Fit the spring mounting clip for snap-in mounting to the switch unit. * Insert the tab of the spring mounting clip into the two grooves on the threaded part of the switch unit. * Be sure to use the two spring mounting clips. Ensure that each tab is firmly inserted onto the grooves. * Do not use the spring mounting clips for the switch unit conforming to IP65. The rubber seal may not be held in close enough contact to prevent the inflow of liquid. Use a nut to secure the switch. * Insert the switch unit from the front of the panel, and push until you hear the clips snap into place. SOCKET MOUNTING * After mounting the switch unit on the panel, secured by the mounting nut, attach the socket to the switch unit. * In doing so, make sure that the projection on the switch unit fits in the positioning hole (at the wider side) of the socket.
