(in this case, the current of the relay coil is the load of the switch.) do not apply a force of 2 kg or higher to the pin plunger. exercise care that the environment conditions such as temperature and humidity do not change abruptly. drip-proof type (z- n n 55) the switch is not perfectly oil-tight; so, do not dip it in oil or water. depending on the environments, the materials of the rubber boots must be selected. oil-tight, cold-resistive, and heat- resistive rubbers are available from omron. flexible rod type (z-15 n n nj n n 55) (drip-proof type) when the rod is fully swung, the switch may operate when the lever returns, causing chattering. use a circuit that compensates for chattering wherever possible. do not switch the rod to the fullest extent when the switch is to break a power circuit because such a practice may cause metal deposition to occur between the mating contacts of the switch. n mounting use m4 mounting screws with plain washers or spring washers to mount the switch. tighten the screws at a torque of 12 to 15 kg-cm. solder the lead to the terminal by applying a soldering iron rated at 60 w max. quickly (within 5 seconds). note that applying a soldering iron for too long a time or using one that is rated at more than 60 w may degrade the switch characteristics. panel mount type (z-15 n n q) when mounting a panel mount type switch (the one having a suffix -q in its model number) to a panel, tighten the hexagon nut of the actuator at a torque of 50 kg-cm or less. when mounting a panel mount type switch on its side, remove the hexagon nut from the actuator and carefully adjust the dog angle and operating speed because too large a dog angle or too high an operating speed may damage the switch. especially be careful not to apply an impulsive force to the actuator when operating it. by the same token, too high an operating speed and too long an overtravel may damage a panel mount switch with a roller pin plunger. do not use mounting holes of the switch body when mounting on panel with m12 mounting nut.
