Voltage detector apparatus

Abstract

A mount is secured to an end of a cylindrical housing with a front side facing outward thereof. A knob is provided having a stem extending from one end and a gear secured to and extending radially outward from the end of the knob. An aperture is formed through the mount for receiving the stem of the knob with the knob located on the front side of the mount near one edge thereof. A generally cylindrical shaped face member has an inner side secured to the front side of the mount and an outer side facing outward thereof. The face member has an opening formed therethrough for receiving the knob and its gear such that the knob may be viewed from the opening from the outer side of the face member. The opening of the face member extends to one edge thereof such that a portion of the gear is accessable from the edge. An annular member is located around the face member and is supported by the face member for rotation in opposite directions relative to the face member. The annular member has gear teeth in mesh with the teeth of the gear of the knob for causing the knob gear and hence the knob to rotate when the annular member is rotated relative to the face member. A stop and a slot are provided on the annular member and face member respectively or vice versa for limiting rotation of the annular member in opposite directions relative to the face member.
