Abstract

A proximity detector switch of the field capacitance type is with the plates of a capacitor not disposed parallel to each other as is usual in such devices. The plates are arranged in a co-planar configuration and separated by a distance which is of a similar magnitude to the capacitive field range. The coplanar plates (16) and (17) are mounted on supports (42) and (43) attached by pillars (44) to a base member (46) with screws (45). The line (40) initiates the capacitive field range in which the switch actuation takes place.
