(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. (fig. 3) cleaning 1. flux clean using vapor degreaser and forced rinse or triple bath method. 2. do not allow switch base to rap?luids. 3. freon tmc, tf or methylene chloride give excellent results. to set stops: turn shaft fully counter-clockwise and insert stop ring tab in desired hole. install lockwasher and nut to retain stop ring for both pc and panel mounting. switch without stop ring has 12 positions. soldering, cleaning and assembly instructions for c?ermination option
