Abstract
A variable resistor and switch assembly in which a variable resistor and a switch are constructed as a unit. The assembly has an insulating substrate, a resistor, a collector and stationary contacts which are formed on the substrate, and a carrier made of an electrically insulating material. The carrier includes a slider for making sliding contact with the resistor and the collector, a pair of contactors made of a resilient metallic material and making sliding contact with respective one of the pair of stationary contacts, and an operation member made of an electrically insulating material and adapted for breaking the conduction between the pair of contactors. As the operation member is actuated at any desired position of the slider, the conduction between the pair of contactors is broken to make the switch take the off state irrespective of the resistance value of the variable resistor.
