Install lockwasher and nut to retain stop ring for both PC and panel mounting. Switch without stop ring has 12 positions. The number of switch positions is adjustable on A112 and A125 models only by means of a stop ring provided with each switch. The number of positions is pre-set on all other models and the stop ring is factory installed. Soldering, Cleaning and Assembly Instructions for ‘MC’ Termination Option Soldering 1. Insert switch base only into PC board. 2. Do not bend terminals. 3. Wave soldering recommended at 500F solder temperature. 4. Hand solder at 500F, 10 sec. max./terminal. Cleaning 1. Flux clean using vapor degreaser and forced rinse or triple bath method. 2. Do not allow switch base to ‘trap’ fluids. 3. Freon TMC, TF or Methylene Chloride give excellent results. REMOVABLE CLIP K Rotary Switch Assembly 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 latches in slots on base. (FIG. 2) 4. Push firmly on housing until latches snap in place. 5. Remove clip from shaft and discard. Assembly is complete.
