Digital multimeter having improved rotary switch assembly

摘要

A multimeter includes a case having a rotary selector knob for selecting a multimeter function. A circuit board defining multiple switching terminals thereon is located in the case. A rotary switch assembly is operatively coupled to the selector knob. The rotary switch assembly has a plurality of contact pairs which selectively complete a galvanic connection across predetermined pairs of switching terminals. The rotary switch assembly further includes first and second switch members located in opposition on respective sides of the circuit board. Each of the switch members has at least one of the contact pairs.
