And Switch is turned OFF by external signal to coil embedded in switch. (1) Signal contact terminal and Power contact terminal are turned ON by manual operation of button. (2) Power contact terminal is kept in ON status, even if button is operated to turn OFF by manual operation. Only Signal contact terminal is turned OFF. (3) Power contact terminal is turned OFF when external signal is applied to coil. Furthermore, it is able to turn OFF both signal and power contact terminals from manual ON condition at the same time by applying voltage to coil as Remote Reset Function.

Or it may result in electric shock. •Handling • Do not apply excessive operating force to the switch. • Do not drop or apply the excessive shock. Otherwise the switch may be damaged or deformed. • Do not impose force to operating part from an angle, Otherwise the switch may be damaged or deformed. Cautions Use the switch within the rated voltage and current ranges, otherwise the switch may have deteriorated durability radiate heat, or burn out. This particularly applies to the instantaneous voltages and currents when switching. Caution of usage •Mounting • Easy to mount by snap fitting. • Do not impose excessive force on switch at the time of panel mounting. • Do not detach the switch after installed. Otherwise, the holding strength may be loose. • Apply the force to housing when installing to panel. Do not apply the force to the button (rocker) part when installing to the panel. Pushing position Correct Incorrect •Environment for storage and use • To prevent the terminals color change and others while storage, Do not keep for a long term in the following conditions. (1) High temperature, high humid environment (2) Corrosive gas (3) The place where the direct rays of the sun (4) The place where the sea breeze (5) Environmental with a sudden temperature change This switch is not sealed to prevent from entering dust and liquid.Do not use under dust and liquid condition. • Switch shall not be icing or condensation. • Strong magnetic field may cause malfunction. Check function is recommended under practical use conditions. •Using Micro Loads •Wiring • Confirm the size of the receptacles and be sure to connect them firmly. • Use an appropriate wire allowable to carry current. • Be sure that there is no mechanical stress on terminals and coil terminals.Otherwise, the switch may malfunction and/or damaged. (Example: Too strong wiring) In case of using the switch under the micro loads, please refer the Minimum applicable load and set the load more than minimum applicable load. Even when using micro load within the operating range, if inrush current occurs, it may increase contact wear and so deteriorate durability.Therefore, insert a contact protection circuit where necessary. The minimum applicable load is the L-level reference value. This value indicates the malfunction reference level for the reliability level of 60 %. (λ 60) The equation, λ 60 = 0.5 x 10-6 /operations indicates that the estimated malfunction rate is less than 1/2,000,000 operations with a reliability level of 60 %. • Take appropriate insulation distance between switch terminal and other metal parts after wiring. • Coil has polarity, please confirm polarity when wiring. • Do not apply continuous voltage more than 10 seconds at any time. Otherwise, insulation deterioration may occur by heat of coil. Please consider the circuit design. • Reverse voltage may cause of accurate discrete semiconductor devices. In case of controlling by accurate discrete semiconductor devices, Please consider the circuit design. (Example : add the surge absorbing circuit) • In case of manual soldering, soldering time is max 4 sec by soldering iron (Max 350 °C at the iron tip) and do not add the stress to terminals. • In case of touching the soldering iron to the root of terminals, it may cause Housing parts melt. 6 •RoHS Compliant The "RoHS Compliant" designation indicates that the listed models do not contain the six hazardous substances covered by the RoHS Directive. Reference: The following standards are used to determine compliance for the six substances. Lead : 1,000 ppm max. Mercury : 1,000 ppm max. Cadmium : 100 ppm max. Hexavalent chromium : 1,000 ppm max. PBB : 1,000 ppm max. PBDE : 1,000 ppm max. MEMO 7 • Application examples provided in this document are for reference only.
