Abstract

The switch is particularly for low current peripheral equipment in information processing and has a flexible tube (2) of some insulating material containing the conducting liquid the contacts being situated at its ends. Operation is by a press button (9) controlling a slide (5) which moves transversely of the tube. The slide has two projections (6, 7) which compress the tube to break the thread of conducting liquid in the tube and thus open the switch. The button engages a return coil spring and the slide is controlled by a snap action leaf spring (8). The button controls the state of the leaf spring so that either projection or no projection is forced against the tube by the leaf spring.
