Electrical Characteristics
Operating Load
switching load capacity Switch greatly varies between Always sure apply rated load. control capacity will drastically drop load. This because load current zero-cross point, unlike load. Therefore, generated, continue comparatively long time. Furthermore, current direction always same, which results contact relocation phenomena whereby contacts easily stick each other separate when surfaces contacts uneven. Some types load have great difference between normal current inrush current. Make sure that inrush current within permissible value. greater inrush current closed circuit greater contact abrasion shift will Consequently, contact weld, contact separation failures, insulation failures result. Furthermore, Switch broken damaged. load inductive, counter-electromotive voltage will generated. higher voltage higher generated energy will which will increase abrasion contacts contact relocation phenomena. sure Switch within rated conditions. performance ratings given operation under following conditions unless otherwise specified. Inductive load: minimum power factor (AC) maximum time constant (DC) Lamp load: inrush current times higher than steady-state current Motor load: inrush current times higher than steady-state current
Note: Inductive loads cause problems especially circuitry. Therefore, essential know time constants (L/R) load.

Consequently, when contacts again, short-circuited current from capacitance cause contact weld. This circuit effectively suppresses arcs when contacts OFF.

Switching inductive load usually more difficult than switching resistive load. using appropriate contact protective circuit, however, switching inductive load will easy switching resistive load.
Switching
Switch loads that exceed rated switching capacity other contact ratings. Doing result contact weld, contact separation failures, insulation failures. Furthermore, Switch broken damaged. touch charged switch terminals while power supplied, otherwise electric shock received. life Switch varies greatly with switching conditions. Before using Switch, sure test Switch under actual conditions. Make sure that number switching operations within permissible range. deteriorated Switch used continuously, insulation failures, contact weld, contact failures, switch damage, switch burnout result. apply excessive incorrect voltages Switch incorrectly wire terminals. Otherwise, Switch function properly have adverse effect external circuitry. Furthermore, Switch itself become damaged burnt. Switch locations where flammable explosive gases present. Otherwise switching arcs heat radiation cause fire explosion. drop disassemble Switch, otherwise capable full performance. Furthermore, broken burnt.

Mounting
Switches broadly divided into categories according mounting method: panel-mounting models PCB-mounting models. appropriate model mounting method required. Basically, panel-mounting Switches withstand greater operating force than PCB-mounting Switches. however, panel thickness panel-cutout dimensions suitable Switch, able withstand normal operating force. With continuous mounting particular, select panel thickness that easily sufficient withstand total operating force. Panel-mounting Switches divided into categories according mounting method: snap-in mounting models screw-mounting models. Snap-in mounting Switches held place with elasticity resin metal leaf spring. attempt modify spring after mounting. Doing result faulty operation damage mounting structure.

place PCBs that have flux applied have been soldered each other. Otherwise, flux PCBs solder surface stain upper part Switch even permeate inside Switch cause contact failure. sure insert special stocker.
Storage
When Switch left unused stored long periods, ambient conditions have great effect condition Switch. certain environments, leaving Switch exposed result deterioration (i.e., oxidation, creation oxide film) contacts terminals, causing contact resistance increase, making difficult solder lead wires. Therefore, store well-ventilated room, inside, example, non-hygroscopic case, location where corrosive gases present.
Flux
place PCBs with solder flux each other.
When performing soldering with soldering bath, ensure that flux does reach higher level than PCB.
Switch stored location where will exposed direct light, colored resin colored plate fade. Therefore, store Switch locations where will exposed direct light.
Flux especially likely rise edges PCB. Switch mounted near edge PCB, create between edge using split PCB, insert soldering bath that edge that farthest from Switch enters bath first.
