Abstract

796,931. Variable resistors. STANDARD TELEPHONES & CABLES, Ltd. Jan. 4, 1957 [Jan. 5, 1956], No. 387/56. Class 37. A variable resistor consists of two main parts, the base plate 1 (Fig. 1) on which are mounted the arcuate resistive track 2 and a circular contact member 5 together with the terminals, and the case moulding which provides a knob 22, limit stops 26 for wiper travel, a mounting 23 for the wiper, and a cylindrical spigot 24 which by turning in a hole in the base-plate provides a rotatable mounting and a means of attachment thereto. The wiper (Fig. 2), is designed so that two sides of the hole 14 engage flats on the spigot 24. The limit stops operate by engaging a pin which is an extension of the terminal for the contact member 5. In another embodiment (Fig. 11), the knob is omitted as the case alone gives sufficient purchase and the wiper used is shown in Figs. 12, 14. The terminal pins may be rectangular.
