Refer to Safety Precautions for All Pushbutton Switches/Indicators. 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. Mounting

• Do not perform wiring with power supplied to the Switch. Do not touch the terminals or other charged parts of the Switch while power is being supplied. Doing so may result in electric shock.
• Always make sure that the power is turned OFF before mounting, removing, or wiring the Switch, or performing maintenance. 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 N·m.
• Recommended panel thickness: 1 to 5 mm.
• When mounting the caps after changing the LED or the caps, tighten the caps at a tightening torque of 0.49 tp 0.78 N·m. Wiring
• Terminal screws must be Phillips or slotted M3.5 screws with a square washer.
• The tightening torque is 1.08 to 1.27 N·m.
• Solid wires, stranded wires, and crimp terminals can be connected to the Switch. Applicable Wire Size Stranded wire: 2 mm2 max. Solid wire: 1.6 dia. max. Bare Crimp Terminals Crimp Terminals with Insulating Sheath
• After wiring the Switch, maintain an appropriate clearance and creepage distance. Operating Environment
• The IP65 model is designed with a degree of protection so that it will not sustain damage if it is subjected to water from any direction to the front of the panel.
• This switch is intended for indoor use only. Using the Switch outdoors will result in failure. LED
• 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. When DC-specific LEDs are used, wire the Switch so that the X1 terminal is positive.
• Mis-lighting of the LED 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 capacity between cables, etc.). Select resistance value and allowable power consumption that meet the actual current. Others
• If the panel is to be finished with coating, etc., make sure that the panel meets the specified dimensions after the coating.
• Do not subject the Switch to extreme shock or vibration. Doing so will cause malfunctions and damage to the Switch. Using the Microload
• 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% (λ 60) (conforming to JIS C5003). The equation, λ 60 = 0.5 x 10 −6/operations indicates that the estimated malfunction rate is less than 1/2,000,000 operations with a reliability level of 60%.

• Panel hole dimensions are given below.
• Recommended panel thickness: 1 to 5 mm.
• For 25-dia. holes, always use 25-dia. Rings. (Since the cutout dimensions are large, IP65 cannot be guaranteed unless 25-dia. Rings are used.)
• If outer surface treatment such as coating is performed for the panel, the panel dimensions after outer surface treatment must meet the specified panel dimensions. Matrix Installation 1. The following panel hole dimensions apply when Switch Unit and the Standard-size Legend Plate Frame and Lock Ring are mounted, and lead wires are connected directly to the Switch Block. 2. The following panel hole dimensions apply when the Large-size Legend Plate Frame is mounted, and when crimp terminals are connected to the Switch Block terminals. For 1. above: For 2. above: Note: 1. The above dimensions are the minimum dimensions for when the wires described under Applicable Wire Size on page 23 are used. If a different wires are used, the wiring dimensions may be different so determine an appropriate pitch before setup. 2. With pushbuttons of external dimensions greater than 30 mm, set the pitch according to the dimensions. (When using matrix installation for the A22-M@, mount with a pitch of 40 mm instead of 30 mm in the diagram above.) Mounting the Operation Unit on the Panel
• Insert the Operation Unit (Pushbutton, etc.) 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 Pushbutton 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. 22.3+0.4 +0.2 +0.4 22.3 25 dia.22 dia. +0.4 0 25+0.5 3.2 24.1 0.8R max.

• Tighten the mounting nut at a torque of 0.98 to 1.96 N·m.
• 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.
• When the panel cutout dimension is 25 dia., remove the supplied rubber washer and mount the 25-dia. Ring as shown below. (Since the A22Z-R25 is not attached to the main body, order separately.) Mounting the Switch on the Pushbutton Unit
• Insert the Pushbutton 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. Removing the Switch
• Move the lever in the direction indicated by the arrow in the following figure, then pull the Pushbutton 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.
