A7MA-207-P2-1 Datasheet A7MA-107-P2, A7MA-207-P2-1, A7M-1M | P1-P3

Thumbwheel Switch A7MA

Economical and Reliable Thumbwheel

Switch in Ultra-Small Size

■ Gold contacts are employed to provide

maximum contact reliability

■ Printed circuit board employs epoxy paper

as the base material, with gold plating over

nickel plate for circuit pattern

■ 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

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.

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.
