4 precautions precautions safety precautions cautions use the dip switch within the rated voltage and current ranges, otherwise the dip switch may have a shortened life expectancy, radiate heat, or burn out. this particularly applies to the instanta- neous voltages and currents when switching. correct use circuit design although the minimum current is 10 a (3.5 vdc), contact reli- ability may need to be improved in some cases. this is particu- larly true when switching causes an increase in instantaneous current, such as in c-mos ic applications. do not let the peak current exceed the rated value here or any other time. only bcd/hexadecimal 1-2-4-8 code is available for a6c/a6cv/ a6r/a6rv models. if bcd/hexadecimal 1-2-4-8 complement code is required, make the appropri ate provisions in the circuit. mounting normally the default striker setting is off for slide-type dip switches and the default rotor setting is 0 for rotary dip switches. do not change these se ttings when mounting, solder- ing, washing or drying switches. in rare cases, the striker may be deformed by heat generated during soldering. 1. automatic insertion machine use a body stopper system for the chute stopper of automatic insertion machines. when mounting switches using an insertion machine incorporating a half-lead stopper, make sure the machine will not deform the terminals of the switch, or improper insertion may result. check actual mounting conditions prior to using a half-lead stopper system. a printed circuit board that is 1.2 to 1.6 mm thick is recom- mended. holes on the pcb should be at least 0.9 mm in diameter for auto- matic insertion. 2. manual or ic socket insertion commercially available insertion tools are recommended for mounting ics on pcbs. terminal pitch, dimensions and other features are identical to that of standard ics for ic socket compatibility (except for the a6s-h and a6h). align the terminals so they slide in simultaneously when the switch is inserted into socket hol es or into mounting holes pre- drilled at the specified dimensions. apply downward force on the switch until the terminals are properly seated on the pcb. do not try to remove a switch by inserting a screwdriver between it and the pcb, and then twisting the screwdriver to peel the switch off. use a commercially available inserter/remover to remove the switch. soldering observe the following conditions when soldering the dip switch. 1. general precautions for soldering make sure that the striker of slide-type dip switches is set fully to either on or off. (for a6e and a6er models, however, set the switch to off before soldering.) make sure that rotary dip switches are correctly set to 0. misalignment may result in reduced sensitivity due to the soldering heat. before soldering the switch on a pcb, make sure there is no unnecessary space between the switch and the pcb. before soldering the switch on a multilayer pcb, conduct a test to make sure the switch will not be deformed by soldering heat on the pattern or land of the multilayer pcb. 2. automatic soldering bath (except a6s-h/a6h) soldering temperature: 260 c max. soldering time: 5 s max. for a 1.6-mm thick, single-side pcb do not use an automatic soldering bath or manual soldering for a6s-h or a6h models. confirm in advance that flux will not bubble up onto the side of the pcb to which the switch is mounted. depending on the type of switch, the flux may have an adverse effect if it enters the switch. the a6s-h and a6h are designed spec ifically for reflow solder- ing. do not use an automatic soldering bath or manual soldering for these models. 3. reflow soldering observe the following conditions for reflow soldering the a6s-h and a6h models. (measurement location: top of switch) do not use reflow soldering for any models other than the a6s-h and a6h. otherwise the plastic case may melt or deform. the soldering conditions and the temperature around the switch may vary with the type of reflow bath. check the temperature pro- file and confirm soldering conditions as well as the amount of heat applied to the switch prior to soldering. 4. manual soldering (except a6s-h/a6h) soldering temperature: 350 c at the tip of the soldering iron. soldering time: 3 s max. for a 1.6-mm thick, single-side pcb do not solder the switch more than twice including any rectifica- tion soldering. an interval of five minutes is required between the first and second soldering. 5. using flux making mistakes in the type of flux or in the amount or method in which it is applied can cause flux to enter the interior of the switch, with adverse effects on switch performance. assess the proper flux, conditions, and methods prior to using it. pcb surface flux surface a6h soldering conditions a6s-h soldering conditions 260 max. 230 180 150 preheating time (s) 60 to 120 60 max. temperature ( c) 250 max. 230 180 150 preheating time ( s ) temperature ( c) 60 to 120 40 max.
5 precautions precautions washing 1. washable and non-washable models the models for which washing are possible are shown in the fol- lowing table. 2. washing procedure ultrasonic cleaning is not availa ble for slide-type dip switches with seal tape. these models may be wiped or dipped into wash- ing agents for one minute maximum. slide-type dip switches with seal tape can be washed as long as the seal tape is not removed or pasted before washing. non-com- pliance here will cause the quality of the seal to decline. washing equipment incorporating more than one washing bath can be used to clean washable models, provided that the wash- able models are cleaned for one minute maximum per bath and the total cleaning time does not exceed three minutes. 3. washing agents apply alcohol-based solvents to clean washable models. do not apply water or any other agents to clean any washable models, as such agents may degrade the materials or performance of the switch. 4. washing precautions do not impose any external force on washable models while washing. do not clean washable models immediately after soldering. the cleaning agent may be absorbed into the incomplete seal through respiration as the switch cools. wait for at least three minutes after soldering before cleaning. do not use washable switches submerged in water or in locations exposed to water. handling 1. slide-type dip switch operation do not apply excessive operating force to the switch. otherwise the switch may be damaged or deformed, and the switch mecha- nism may malfunction as a result. apply an operating force not exceeding 9.8 n. (operate each pole separately.) apply the oper- ating load from the side of the striker. do not apply a load from an angle or from above the striker. doing so may deform the switch contact. set slide-type dip switches with a tiny, rounded object, such as the tip of a ball-point pen or a small screwdriver. do not set the dip switch using tweezers or any other sharp object that may damage it. do not set the dip switch using the point of a mechan- ical pencil, or lead powder or fragments may fall into the switch and internal circuit board, causing the dip switch to malfunction and reducing the dielectric strength of the circuit board. although raised-type and piano-type strikers can be operated by fingertip, do not push too hard or too fast because this will deform or damage the striker. when setting or operating the a6h, use narrow-headed tweezers or similar implement (without a sharp end), to enable smooth, horizontal operation. pushing the striker at an angle, or applying excessive load from above may damage or deform the striker and thereby prevent operation. 2. rotary dip switch operation set rotary-type dip switches with a flat-blade screwdriver that fits into the screwdriver groove. using a screwdriver of inappropriate dimensions, or using a tool other than a flat-blade screwdriver may cause damage to the groove that may make the switch impossible to operate. insert the flat-blade screwdriver vertically to operate the switch. the switch may be damaged if the screwdriver is inserted at an angle. do not use excessive force to operate the switch, or it may dam- age or deform the switch. 3. setting set the switch to the correct position before use. an incorrectly aligned position may result in incorrect signals. rotary dip switch operation washable a6a, a6c, a6cv, a6d, a6dr, a6t (with seal tape), a6s-h (with seal tape), a6h (with seal tape) non-washable a6r, a6rv, a6t (standard/raised actuator), a6s- h (standard/raised actuator), a6e, a6er incorrect correct item a6r/a6rv a6a a6c/a6cv top/side operation, flat type standard type, flat type shaft type, wheel type top/side operation type screwdriver groove applicable screwdriver: a 1.8 to 2.1 3.5 to 3.8 2.0 to 2.4 applicable screwdriver: b 0.7 to 0.8 0.4 to 0.5 0.5 to 0.6 part names 1.0 2.9 depth: 1.0 depth: 0. 9 0.65 4 de p th: 0.9 0.7 4 dia. de p th: 1.0 2.5 0.8 flat-blade screwdriver groove a6a, a6c/a6cv, a6r/a6rv rotary dip switch a b
