Housing for use with a variable resistor

摘要

A housing for use with a variable resistor consisting of a spiral resistance element, a rotary shaft, a conductive slide plate and a top is disclosed. The housing includes a cylindrical body for supporting on its inner surface the resistance element, a first cylindrical panel engaged with one open end of the cylindrical body to close the open end and rotatably supporting the rotary shaft, a second cylindrical panel engaged with the other open end of the cylindrical body and rotatably supporting the rotary shaft, at least one pair of resilient engaging projections extended from at least one of the first and second cylindrical panels along the axis of the cylindrical body, and engaging recesses formed on an outer periphery of the cylindrical body at predetermined positions and respectively engaging with the resilient engaging projections when the first and second cylindrical panels are engaged with the cylindrical body to make up the housing for the variable resistor.
