Precautions
◆Solderlng
⑴ Manual soldering
- Device：Solder iron ① 270℃ max. 5 sec. max.
⑵ Auto soldering
- Device：Jet wave or dip type
- 245 土10℃ 5 sec. max.
- Preheat time shall be 30 seconds max. at 100℃ max.
- For the alternate action switches, soldering should be done with the switch in the up position.
◆Flux Cleanlng
- Solvent : Fluorine or Alcohl type.
- The LP series are not washable. To wash the PC board, clean the soldering surface of the PC board with a brush so that the switch is not exposed to the cleaning solution.
- After soldering, wait until the temperature of the terminals cool down to 90℃ or below or until the parts are exposed to room temperature for more than 5 min. before washing.
◆Acuator(Cap)
- To activate the switch, press the cap as far as it goes. If the cap is not fully actuated, switching and/or locking may not occur. The pressing force of the cap should be 9.8 N or less.
- Use a soft cloth with alcohol to clean the cap surface. Do not allow the liquid to enter the switch body. Do not use thinner, acid, organic solvent, etc., since the caps and fi lter are made of a polycarbonate resin.
- Engraving or printing is possible on the cap and the fi lter. The engraving depth should be 0.3 mm maximum and the enamelbased paint should be within the coating thickness of 0.1 mm maximum.
- A film insert should be the size of the dimensions as shown in the fi gure on the left (t=0.1mm). The fi lm inserts are provided by the customer.
- The cap and the fi lter are two distinct parts. Removal of the cap should be done with the in the up position to avoid damages to the switch.
◆LED's
- The polarity of the LED is marked on the bottom of the switch. Connection should be made as marked.
- Protective resistors are not built into illuminated switches. Protective resistors must be integrated by the customer.
- LED specifications are shown on.
Mounting Procedures
⑴ Removal of the cap
Use the notch on the side of the cap and pull up. Remove the cap with the switch in the up position.
⑵ Mounting the cap
A) Insert the fi lter into the cap. The fi lter is reversible.
B) Mate and snap in the two recesses on the inner side of the cap to the tabs on the side of the actuator of the switch.
⑶ Mounting the Switch Guard
⑷ Panel cutout
- When cutting out the panel, press through the panel from the front side.
- Also make sure to mount the switch from the front side of the panel as shown in the fi gure below. This will help the mount spring on both sides of the switch latch on to the edge of the hole.
- Note that the vertical play of the switch when mounted is 0.3 mm max..
