2 long stroke tactile switch b3al construction dimensions note: unless otherwise specifi ed, all units are in millimeters and a tolerance of 0.4mm applies to all dimensions. precautions precautions for correct use handling soldering do not exceed the following term inal temperature profile during soldering in a reflow oven. washing the switches are not sealed, and cannot be washed. doing so will cause the washing agent, together with flux or dust particles on the pcb, to enter the switch, resulting in malfunction. packaging specifications the packaging specifications fo r b3al switches in embossed taping are given below. p u sh bu tton pl u nger mo v ing contact terminal (contact) base 4.9 dia. pcb pad (top view) terminal arrangement / internal connections (top view) 8 4 2 6.6 0.8 5 6.9 5.8 6 1.4 260 c 220 c 180 c 150 c 60 to 120s 60s max. time preheating time main heating time (22) (5.5) reel 13 di a. 1.5 dia. +0.1 0 380 2 dia. 1.75 tape drawing direction tape drawing direction 40.1 c c cross section c-c 120.1 2 16 7.50
long stroke tactile switch b3al 3 operation ? do not repeatedly operate the switch with excessive force. applying 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 pressed off-c enter or from an angle it may cause deformation or damage to some parts. ? we recommend using a round bar with a diameter of at least 3 mm as the actuator. dust countermeasures do not mount or use the switch in areas that are subject to dust. if dust is unavoidable, protect the switch with a sheet or other countermeasure. water and drip resistance the switch is not water or drip resistant. do not use it in locations subject to water. common precautions be sure to read the precautions common to all tactile switches, con- tained in the technical user?s guid e, ?tactile switches, technical information? for correct use.
