AEQ (EQ) Switches

The application of excessive heat upon the switch when soldering can cause degradation of switch operation. Therefore, be sure to keep within the conditions given below. Manual soldering: use soldering irons (Max. 350°C, within 3 seconds at each terminal) capable of temperature adjustment. This is to prevent deterioration due to soldering heat. Care should be taken not to apply force to the terminals during soldering. (More than one second interval is required to apply heat at each terminal.) Please consult us if you intend to use a soldering iron that exceeds 60 W.

Please avoid use in which load would be applied to the sides [hatch part (both sides) shown below] of the switch in the direction indicated by the arrows. This could cause erroneous operation. Also, when using a metal installation board, please make allowance for burr direction designation and burr suppressing, etc., so that the burr side will not be on the switch installation side.

• 1.To secure the switch, please use an M3 small screw on a flat surface and tighten using a maximum torque of 0.29N·m. It is recommended that spring washers be used with the screws and adhesive be applied to lock the screws to prevent loosening of the screws. Please make sure not to apply adhesive onto the moving parts.
• 2.Be sure to maintain adequate insulating clearance between each terminal and ground.
• 3.Although it is possible to directly operate the pin plunger type from the lateral direction, please consult us if doing so.
• 4.After mounting please make sure no tensile load will be applied to the switch terminals.
• 5.Range of possible use: Please set the operation position to within the ranges in the following table so that there is sufficient insulation distance and to maintain contact reliability.

Actuator	Plunger/lever free
	From boss and hole center line	From standoff
Pin plunger	>9.2 mm	>13.4 mm
Leaf lever	>10.7 mm	>14.9 mm
Simulated leaf lever	>13.5 mm	>17.7 mm

Actuator	Plunger/Lever pushed
	From boss and hole center line	From standoff
Pin plunger	7.8 to 5.9 mm	12.0 to 10.1 mm
Leaf lever	8.4 to 6.2 mm	12.6 to 10.4 mm
Simulated leaf lever	11.1 to 8.7 mm	15.3 to 12.9 mm

• 6.P/C board terminal type should be used if the products are to be soldered on the P/C board. (Solder terminal type is not for soldering on P/C board.)

• 1.In order to prevent malfunction in set devices caused by bounce and chattering during the ON-OFF switch operation, please verify the validity of the circuit under actual operating conditions and temperature range.
• 2.When switching inductive loads (relays, solenoids, buzzers, etc.), an arc absorbing circuit is recommended to protect the contacts.

Please be sure to conduct quality verification under actual operating conditions in order to increase reliability during actual use.

Please make your selection so that there will be no problems even if the operating characteristics vary up to ±20% from the standard values.

• 1.Keep away from environments where silicon based adhesives, oil or grease are present as faulty contacts may result from silicon oxide. Do not use in areas where flammable or explosive gases from gasoline and thinner, etc., may be present.
• 2.When using the lever type, please be careful not to apply unreasonable load from the reverse or lateral directions of operation.
• 3.Do not exceed the total travel position (TTP) and press the actuator. This could cause operation failure. Also, when switching at high speed or under shock even within the operation limit, the working life may decrease. Therefore, please be sure to verify the quality under actual conditions of use.
• 4.Please make considerations so that the switch does not become the stopper for the operating part. The switch could break.
