7 b3w-9 b3w-9 safety precautions note: refer to safety precautions in tactile switches (cat. no. x037) for details on general safety precautions. precautions for correct use electrical standards use the switch within the rated voltage and current ranges, other- wise the switch may have a shortened life expectancy, radiate heat, or burn out. this particularly applies to the instantaneous voltages and currents when switching. soldering 1. soldering precautions before any kind of soldering, test to confirm that soldering can be performed properly. otherwise the switch may be deformed by the soldering heat depending on the type of pcb, pattern, or lands of the pcb. do not solder the switch more than twice, including rectification soldering. wait for at least five minutes between the first and sec- ond soldering to allow the temperature to return to normal. con- tinuous soldering may cause the casi ng to melt or deteriorate the switch characteristics. 2. automatic soldering baths (wave soldering) soldering temperature: 260 c max. soldering time: 5 s max. for a 1.6-mm thick single-side pcb preheating temperature: 100 c max. (ambient temperature) preheating time: within 60 s precautions make sure that no flux will rise above the level of the pcb. also make sure that flux is not applied to the switch terminals or to the mounting surface of the pcb. if flux overflows onto the mounting surface of the pcb, it may en- ter the switch and cause a malfunction. 3. manual soldering soldering temperature: 350 c max. at the tip of the soldering iron soldering time: 3 s max. for a 1.6-mm thick, single-side pcb precautions: before soldering the switch on a pcb, make sure that there is no unnecessary space between the switch and the pcb. washing standard switches are not sealed, and cannot be washed. doing so will cause the washing agent, together with flux or dust parti- cles on the pcb, to enter the switch, resulting in malfunction. pcbs the switch is designed for a 1. 6-mm thick, single-side pcb. using pcbs with a different thickness or using double-sided, through-hole pcbs may result in loose mounting, improper inser- tion, or poor heat resistance in so ldering. these effects will occur, depending on the type of holes and patterns of the pcb. there- fore, it is recommended that a verification test is conducted before use. handling 1. usage environment before installing the switch, make sure that the area of installa- tion is not subject to corrosiv e gases emitted from surrounding parts. do not use in areas subject to high temperatures, high humidity, or toxic gases such as sulfuric gas (h 2 s, so 2 ), ammonia gas (nh 3 ), nitric gas (hno 3 ), or chlorine gas (ci 2 ). it can cause corro- sive damage to the contacts and result in malfunction. if there is silicon in the atmospher e, it may stop the contacts from functioning properly. if silicon products, such as silicon oil, silicon f iller, or silicon wires, are used in the surrounding area, in stall a contact protection cir- cuit to prevent arching or remove the silicon source. the following situations may cause water to enter inside the switch, resulting in a malfunction due to contact failure or corro- sion. using the switch in an outdoor environment where it is exposed to water drops for an extended period of time. using the switch in an underwater setting where it is subject to strong water pressure. do not use switches that have been dropped. the mating section or other internal parts may be dam aged, resulting in malfunction. operation do not repeatedly operate the switch with excessive force. apply- ing excessive pressure or applying additional force after the plunger has stopped may deform the disk spring of the switch, resulting in malfunction. be sure to set up the switch so that the plunger will operate in a straight vertical line. if the plunger is press ed of-center or from an angle it may cause deformation or damage to some parts. this may result in deterio- ration of durability or malfunction. dust protection do not install or use switches in dust-prone environments. if a switch must be used in this kind of environment, use a protective sheet or take other measures to protect it against dust. note: switches with high-brightnes s green (hg) or blue (b) leds are susceptible to static electricity. be careful when handling a switch with these leds as it may cause the switch to breakdown.
b3w-9 b3w-9 removing the cap 1. hold the cap at the side away from the mating section. pull straight up. 2. do not remove the cap while the switch is mounted. doing so will apply force to the soldered section and leds, result- ing in malfunction. placing the cap on the switch hold the cap at the side away from the mating section. push straight down until the mating section meets. removing the cap the cap can be removed up to two times. excessively removing the cap will cause the mating se ction to become weak, resulting the operating section not mating completely or the cap may fall off. film dimensions dimensions of the film are show n below. the thickness is 0.2 mm. storage precautions storage environment to prevent degradation, such as discoloration, of the terminals during storage, do not store the switch in locations that are sub- ject to the following conditions. 1. high temperature or humidity 2. corrosive gases 3. direct sunlight storage condition store the switches in the packaging box. after the packaging box is opened, use the contents as quickly as possible. when storing leftover parts, make sure that appropriate measures are taken against humidity and corrosive gases. agreement of product use comply with the usage, storage , and disposal conditions speci- fied by omron as outlined in the precautions in the product datasheet and specifications. correct incorrect correct incorrect 7.4 0.1 8.9 0.1 8.9 0.1 7.4 0.1 in the interest of product impr ovement, specifications are subj ect 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. a167-e1-04 omron corporation electronic components company switch division manual switch department shiokoji horikawa, shimogyo-ku, kyoto, 600-8530 japan tel: (81)75-344-7096/fax: (81)75-344-7188 0509
