Cautions For Use

Turquoise Stroke Mini Switches Cautions for Use

■Soldering conditions

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) 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.

■Mounting

<Important>To prevent deterioration of contact reliability due to the deformation of the fork terminal, the fork terminal switch should be mounted by using the special tooling to keep the switch in the vertical state to the actual equipment and insert the terminal while supporting the terminal part with the tooling (Please see the below).
<Important> Be sure to apply a sealing material to the terminal part, fix the switch completely and seal the terminal part to prevent deterioration of contact reliability in the connected part by the fork terminal of the switch and the terminal of the actual equipment due to vibration, impact, humidity and gas. (An unsealed switch should not be used.) Additionally, it is necessary to select a sealing material which does not cause sulfuration, oxidation or generation of low molecular siloxane gas because there is a risk that contact failure occurs due to sealing materials. For the selection of a sealing material, the sufficient verification by using the actual equipment should be implemented in advance.
<Important>The contact reliability at terminal connecting portion may highly deteriorate because of using unmatched material or size accuracy of connected side terminals or inadequate switch insertion method. Please make sure to consult us if you consider using fork terminal type.
To secure the wire leads type switch, please use M3 small screws on a flat surface and tighten using a maximum torque of 0.29 N·m. Be sure to verify the quality under actual conditions of use because the switch plastic might be deformed according to that the kind of the screw (size of screw head etc.), the diameter of the washer and the presence of washer. And use of adhesive lock is recommended to prevent loosening of the screws. When using an adhesive, care should be taken not to invade the adhesive into the switches.
Be sure to maintain adequate insulating clearance between each terminal and ground.
After mounting please make sure no pulling load will be applied to the switch terminals.
The positioning of the switch should be such that direct force is not applied to the plunger or actuator in its free position. The operating force to the plunger should only be applied in a perpendicular direction.
When slanted press operation is applied to pin plunger type switches by an operation cam, the endurance life may greatly vary depending on the use of grease for sliding, operation angle, operation speed, operation frequency, press amount of the pin plunger, cam material, cam shape, cam surface condition, etc. Therefore fully verification by using the actual equipment in advance should be implemented.

■Cautions regarding the circuit

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.
When switching inductive loads (relays, solenoids, buzzers, etc.), it is recommended that contact protection element such as diode, varistor, etc., is introduced to prevent contact failure caused by electric discharge.

■Please verify under actual conditions.

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

■Selection of switch

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

■Oil-proof and chemical-proof characteristics

Do not use alcohol-based solvents.
The rubber cap swells when exposed to oil and chemicals. The extent of swelling will vary widely depending on the type and amount of oil and chemicals.
Check with the actual oil or chemicals used. In particular, be aware that solvents such as freon, chlorine, toluene, etc., cannot be used.

■Operation environment

Although continuous operation of the switch is possible within the range of ambient temperature (humidity), as the humidity range differs depending on the ambient temperature, the humidity range indicated below should be used.
Continuous use near the limit of the range should be avoided.
This temperature-humidity range does not guarantee permanent performance.

■Others

Do not handle the switch in a way that may cause damage to the sealing rubber cap.
Please remember that this switch cannot be used under water. Also, pleased be warned that switching and sudden temperature changes with the presence of water droplets can cause seepage into the unit.
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.
When using the lever type, please be careful not to apply unreasonable load from the reverse or lateral directions of operation.
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.
If the switch is used while the plunger is pressed all the time, the performance of switching release may largely deteriorate due to surrounding temperature and humidity, adherence of oils such as oil, grease, etc., solvents and chemicals. Please be sure to verify the quality under the actual use conditions.
Please make considerations so that the switch does not become the stopper for the moving part.
Do not use the switch which was dropped by mistakes when handling. If it is used, abnormal operation characteristics and sealing performance may occur.
In case of applying coating to movable parts (actuator, plunger, etc.), the quality of the product is not guaranteed because it may cause a product failure.
In case of cleaning a switch, the quality of the product is not guaranteed because it may cause a product failure.
Do not apply ultrasonic vibrations and high frequency vibration to a switch because it may have an impact on the characteristics of the switch.
Please do not constantly apply a tensile load to wire leads when fixing them.
