(3) mounting the operation unit on the panel ? insert the operation unit from the front surface of the panel, insert the lock ring and the mounting nut from the terminal side, then tighten the nut. before tightening, check that the rubber washer is present between the operation unit and the panel. ? when using a legend plate frame, put one rubber washer each between the legend plate frame and the panel and between the operation unit and the legend plate frame. (one rubber washer will be provided when one legend plate frame is ordered.) ? align the lock ring with the groove in the casing, then insert the lock ring so that its edge is located on the panel side. ? tighten the mounting nut at a torque of 0.98 to 1.96 nm. ? when using a lock ring, replace with the supplied lock ring, insert the projecting part into the lock slot, and then tighten the mounting nut. (4) mounting the switch on the operation unit ? insert the operation unit into the switch unit, aligning the arrow mark inscribed on the case with the lever on the switch blocks, then move the lever in the direction indicated by the arrow in the following figure. (5) removing the switch ? move the lever in the direction indicated by the arrow in the following figure, then pull the operation unit or the switch blocks. since the lever has a hole with an inside diameter of 6.5 mm, the lever can be moved in the specified direction by inserting a screwdriver into the hole and then moving the screwdriver. 22.3 +0.4 0 dia. 25 +0.5 0 dia. 22.3 +0.4 0 dia. 24.1 +0.4 0 3.2 +0.2 0 r0.8 max. with lock rin g without lock rin g 1. the following diagram provides the dimensions for mounting individual switches, legend plates, and lock rings with leads connected directly to switch terminals. 30 a 2. the following diagram provides the dimensions for mounting large legend plates with crimp terminals connected to switch terminals. 30 b dimensions a and b between mounting hole centers are given in the following tables . for 1., above for 2., above note: 1. the above dimensions are the minimum dimensions when using the applicable wiring materials listed on page 19. if any other materials are used, check the suitability of dimensions in advance. 2. when using pushbuttons exceeding 30 mm, adjust dimension a or b accordingly.

a22e safety precautions be sure to read the precautions for all pushbutton switches in the pushbutton switches group catalog (cat. no. x018). !caution precautions for correct use mounting ? always make sure that the power is turned off before wiring the switch. also, do not touch the terminals or other current-carrying ports while power is being supplied. electric shock may occur. ? do not tighten the mounting ring more than necessary using tools such as pointed-nose pliers. doing so will damage the mounting ring. the tightening torque is 0.98 to 1.96 nm. ? recommended panel thickness: 1 to 5 mm. wiring ? when dc-specific leds are used, wire the switch so that the x1 terminal is positive. ? terminal screws must be phillips or slotted m3.5 screws with a square washer. ? the tightening torque is 1.08 to 1.27 nm. ? single wires, stranded wires, and crimp terminals can be connected to the switch. ? applicable wiring materials: twisted strands: 2 mm 2 max. solid wire: 1.6 mm dia. ? after wiring the switch, maintain an appropriate clearance and creepage distance. operating environment ? the ip65 model is designed with a protective structure so that it will not sustain damage if it is subjected to water from any direction to the front of the panel. leds ? the led current-limiting resistor is built-in, so internal resistance is not required. ? if commercially available leds are used, select the ones that meet the following conditions: base: ba9s/13 @ overall length: 26 mm max. power consumption: 2.6 w max. using the microload ? contact failure may occur if a switch designed for a standard load is used to switch a microload. use switches within the application ranges shown in the following graph. even within the application range, insert a contact protection circuit, if necessary, to prevent the 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% ( o 60) (conforming to jis c5003). the equation, o 60 = 0.5 x 10 6 /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 coated, make sure that the panel meets the specified dimensions after coating. ? due to the structure of the switch, severe shock or vibration may cause malfunctions or damage to the switch. also, most switches are made from resin and will be damaged if they come into contact with sharp objects. particularly scratches on the operation unit may create visual and operational obtrusions. handle the switches with care, and do not throw or drop them. do not apply a voltage exceeding the rated voltage across the incandescent lamp terminals. the lamp may be destroyed and the operation unit may fly out. 8 mm max. 16.0 mm max. 8 mm dia. max. 16.0 mm max. naked crimp terminals 20.2 mm max. 8 mm max. 20.2 mm max. 8 mm dia. max. crimp terminals with insulating sheaths invalid area 0.1 1 10 100 1,000 10 ma 1 ma 5 12 24 30 0.16 ma 1.6 ma 100 ma 0 voltage (v) microload area area of use standard load area current ( ma ) hammer screwdriver do not allow the switch to drop and hit the floor. do not place or drop heavy objects on the switch. do not operate the switch with hard or sharp objects. in the interest of product improvement, specifications are subject to change without notice. all dimensions shown are in millimeters. to convert millimeters into inches, multiply by 0.03937. to convert grams into ounces, multiply by 0.03527. cat. no. a119-e1-06 http://www.ia.omron.com/ 19 (c)copyright omron corporation 2007 all rights reserved.
