detection switch d3c 47 precautions be sure to read the precautions and information common to all snap action and detection switches, contained in the technical us er?s guide, ?snap action switches, technical information? for correct use. correct use mounting turn off the power supply before mounting or removing the switch, wiring or performing maintenance or inspection. failure to do so may result in electric shock or burning. mount the switch onto a flat surface. mounting on an uneven surface may cause deformation of the switch, resulting in faulty operation or breakage in the housing. application of operation force to the lever apply operation forces to the lever in its operating direction. applying operating force to the lever in any other directions will damage the switch or cause malfunction. mounting plate use materials other than abs or polycarbonate for the mounting plate. since grease is used within the switch, cracks may be caused if grease from the switch comes in contact with such materials. using microloads using a model for ordinary loads to switch microloads may result in faulty operation. instead, use t he models that are designed for microloads and that operate in the following range; however, even when using microload models within the operating range shown above, if inrush current or inductive voltage spikes occur when the contact is opened or closed, then contact wear may increase and so decrease the service li fe. therefore, insert a contact protection circuit where necessary. cautions terminal connection when soldering the lead wire to the terminals, first bind the lead wire to the terminal and then apply the 60 (sn):40(pb) solder to the termi- nals. complete soldering within 5s at a soldering iron temperature of 260 c. soldering at a temperature exceeding 260 c, soldering for more than 5 s, or repeated solderi ng will degrade the switch charac- teristics. when soldering the lead wire to the pcb terminal, pay careful atten- tion so that the flux and solder liquid level does not exceed the pcb level. it is also recommended that you apply flux guard to the mounting sur- face of the switch. incorrect incorrect incorrect correct operating range inopera b le range c u rrent (ma) v oltage ( v ) 0.16 ma 100 ma 1,000 100 1 10 30 24 12 5 0 0.1 1ma s w itch mo u nting s u rface
