| Thumbwheel Switch Easy-to-Assemble Thumbwheel Switch Designed Specially for Printed Circuit Boards The transparent window plate fitted in the readout section protects dial characters from dust and prevents wear by incorrect handling s Plus (+) and minus (-) pushbuttons for positive forward and reverse rotation of each digital wheel s The contact section is of dust-proof construction s Switch units can be assembled simply by fitting the integral hook coupler of each unit into the mating unit, thus eliminating the need of nuts and bolts for assembly s A7CN Ordering Information s SWITCH UNITS Part Number Back mounting PC board Light gray case Black case - A7CN-106-1 Front mounting PC board Light gray case Black case A7CN-206 A7CN-206-1 Output Code 06 (binary code) s ACCESSORIES Part Number For back mounting type switch assembly Light gray Black - A7CN-1M-1 - A7CN-1Ps -1 s For front mounting type switch assembly Light gray Black A7CN-2M A7CN-2M-1 A7CN-2Ps s A7CN-2Ps -1 s Accessory End Cap Spacer Note: 1. When placing your order, please specify the model numbers and quantities of required switch units, end caps, and spacers, respectively. (Note that switch units and accessories are not factory-assembled for shipment.) 2. Switch case, end cap, and spacer are made of polyacetal resin; however, the window plate is made of polycarbonate resin. 3. One of the following alphabetic codes must be filled into the boxed part of the model number to specify a legend to be hot stamped on the required spacer. 4. End caps come as a set -- left and right.
