Flux clean using vapor degreaser and forced rinse or triple bath method. 2. Do not bend terminals. 2. Do not allow switch base to ‘trap’ fluids. 3. Wave soldering recommended at 500F solder temperature. 3. Freon TMC, TF or Methylene Chloride give excellent results. 4. Hand solder at 500F, 10 sec. max./terminal. REMOVABLE CLIP Switch Assembly K 1. Hold housing/shaft assembly by housing. Remove protective cap by squeezing tabs and discard. (FIG. 1) 2. Do not push on switch shaft. Detent mechanism will come apart. 3. While holding switch housing, align locating tab on base with notch on housing and engage 4 housing (FIG. 1) LOCATING latches in slots on base. (FIG. 2) TAB 4. Push firmly on housing until latches snap in place. 5. Remove clip from shaft and discard. Assembly is complete.
