The operating load is an induction load.2. The length of wiring to the load is 5 m or more.3. The load voltage is 100 VAC.Use a contact protection box in any of the above situations.The life of the contacts may otherwise be reduced. (They may stay ONall the time.)SpecificationsPart numberLoad voltageMaximum load currentCD-P11100 VAC 200 VAC25 mA 12.5 mA∗ Lead wire lengthSwitch connection side 0.5 mLoad connection side 0.5 mCD-P1224 VDC50 mAInternal circuitsCD-P11Surge absorberChokecoilOUT BrownOUT BlueCD-P12Zener diodesChoke coilOUT (+)BrownOUT ()BlueDimensionsConnection25To connect a switch to a contact protection box, connect the lead wirefrom the side of the contact protection box marked SWITCH to the leadwire coming out of the switch. Furthermore, the switch unit should be keptas close as possible to the contact protection box, with a lead wire lengthof no more than 1 meter between them.

However, dependingon the number of switchesin the ON state, the indicatorlights may sometimesget dark or not light up,because of dispersion andreduction of the current flowingto the switches.26
