Thumbwheel Switch A7CN Easy-to-Assemble Thumbwheel Switch Designed Specially for Printed Circuit Boards I The transparent window plate fitted in the readout section protects dial characters from dust and prevents wear by incorrect handling I Plus (+) and minus (­) pushbuttons for positive forward and reverse rotation of each digital wheel I The contact section is of dust-proof construction I 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 Ordering Information I SWITCH UNITS Part number Back mounting PC board Light gray case Black case ­ A7CN-106-1 A7CN-106-1 Front mounting PC board Light gray case Black case A7CN-206 A7CN-206 A7CN-206-1 A7CN-206-1 Part number For back mounting type switch assembly Light gray Black ­ A7CN-1M-1 ­ A7CN-1PI -1 I Output Code 06 (binary code) For front mounting type switch assembly Light gray Black A7CN-2M A7CN-2M-1 A7CN-2PI I A7CN-2PI -1 I I ACCESSORIES 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.
