Use of screw washers or adhesive lock is recommended. Before mounting, check insulation distance between terminals as well as between terminals and ground. If enough distance is not secured, it is recommended to use insulation material in mounting. Set 70 to 100% overtravel in actual use. When the operation object is in the free position, force should not be applied directly to the actuator or to the pin plunger. Also force should be applied to the pin plunger from vertical direction to the switch. 2. When specifying NV switches, allow ±20% to the listed operating and release forces. 3. Hand soldering should be accomplished in less than seconds, preferably with a 60 watt iron. Avoid contacting the switch case with the soldering iron. 4. Low-level circuit type is recommended for using under low-level current and voltage.. Avoid using NV switches in the following conditions: In corrosive gases, such as hydrogen sulfide. In flammable or explosive gases such as gasoline or thinner etc. In a dusty environment. In an ambient temperature under 2 C 13 F or over 80 C 176 F. In an ambient humidity over 8% R.H.. 74
