compress the terminal 46a and will be detented in the arcuate portion 62. The contact
46a will be resiliently deflected in cantilever fashion by its engagement with the contact
19 to assure good electrical connection therewith. The contact portion 24 of contact 25
will engage and compress the terminal 48a, resiliently deflecting the terminal in
cantilever fashion to establish good electrical contact therewith. Accordingly a circuit
path will be completed from the circuit path 54 to terminal 46, through contact 19,
across the diode 34, through contact portion 26, through terminal 48a and through
circuit path 56; with the diode 34 controlling the current direction of said circuit path in
the well known operation of a diode. Figure 4 illustrates an alternative position of the
knob 30 which is obtained by pivoting the knob about its axle 32. In this position the
contact portion 24 of the contact 25 will be disengaged from the terminal portion 48a of
the terminal 48 thereby interrupting the circuit path heretofore described. In this
position the knob, the contact portion 22a will be disengaged from the terminal portion
46a and the contact portion 22b of the contact 19 will be pivoted to engage and detent
in the arcuate portion 62. Accordingly the knob 30 may be detented in either of two
positions either interrupting or completing a circuit path as described with the diode 34
controlling the direction of current flow or serving to isolate the voltages of undesired
polarities from a circuit path which is established across the terminals 46 and 48.
