A transducer wherein a brush arm is supported for pivotal movement of its distal end along a bank of terminals in a circuit where there is a common terminal and a bank of terminals by expansion and contraction of a bellows. Brushes at the proximal and distal ends of the brush arm are yieldably held engaged with the bank of terminals at the distal end and the common terminal at the proximal end for adding resistances to and removing resistances from the circuit in proportion to changes in pressure. The bellows is supported in a capsule for linear expansion and contraction and contains an open end for receiving, a plug mounting the circuit, brush arm, and linkage as a unit, into operative relation to the bellows, said linkage providing for converting the linear movement of the bellows to rotational movement of the brush arm and for adjustment of the range of movement of the brush arm along the bank of terminals.
