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. 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.
