ABSTRACT:
A pneumatic switch includes a housing which presents external contacts spaced apart to engage a component site on a device such as a circuit board. A pair of components are supported on the switch housing. A flexure mounted armature or vane is biased in one direction to electrically connect one of the pair of mounted components serially between the housing external contacts, while an air flow to the switch displaces the vane to electrically connect the other of the pair of components in series between the external contacts. The electrical leads between each of the pair of components and the external contacts are of equal length. The switch external contacts may also engage the terminals of a component at a circuit site to insert the mounted components alternatively in parallel with the existing component.
