Abstract
646,381. Press-button retractive switches; tumbler switches. BEKA ST. AUBIN AKT.- GES. April 25, 1947, No. 11141. Convention date, May 9, 1946. [Class 38(v)] A switch for use with a dictating device has an " off " position and three " on " positions, providing for (a) forward movement for dictation, (b) backward movement Fig. 2 (not shown), and (c) reproduction. Fig. 1 shows the latter position, wherein a roller 5 on a switch key 1 bridges a contact 9 and a spring 6, which the roller engages continuously. In its opposite position, Fig. 2 (not shown), the roller bridges contacts 6, 8. In its central position, with a slidable part 1 of the switch key retracted, Fig. 1 (not shown), the switch is " off ". The part 1 may, however, be depressed to push spring 6 against a contact 7, and may be latched in this position by pivoting the key 1 in the direction of the arrow, Fig. 3, so that a projection 8a of contact 8 engages a hoook 10 at the end of the key 1.
