csm_a7d_a7dp_ds_e_3_1 1 thumbwheel switch a7d/a7dp ultra-small, low-cost, push-operated switches ? all-in-one design means fewer parts are required. this product delivers high reliability at a low cost. ? uses long-lasting resin springs to achieve a long mechanical durability expectancy of 30,000 operations. ? models with stoppers for restrictin g the setting range are available. ? the series includes a complete range of pen-push models that prevent accidental operation. ordering information switches (single switch units) note: 1. the classification diagrams show 4 switch units combined with end caps to create 4-digit displays. 2. the model numbers given above are for 1 switch unit. 3. models with stoppers are also available. add ?-s @@ ? after the ?106? or ?206? in the model number and specify the display range in the @@ . for example, to specify the range 0 to 6, add ?-s06? to the model number (e.g., a7d-106-s06-1). 4. models with +, - displays are also available. add ?-pm? after the ?106? or ?206? in the model number (e.g., a7d-106-pm or a7d -106-pm-1). accessories (order separately) use accessories, such as end caps and spacers, with the switch units. note: the @ in the spacer model number stands for a letter in the range a to u. (refer to the table in the following explanation about spa cers.) * the minimum order is for 10 end caps. end caps end caps are used on the switch units at each end and allow all t he switch units to be securely mounted to a panel. they come i n pairs, one for the left and one for the right. spacers ? spacers are used for creating extra space or gaps between the switch units and have the same dimensions as the switch units the mselves. ? there are also spacers with engr aved characters or symbols that can be used for indicating units, such as time and length.
