Abstract
A tilt-actuated switch features a housing 11 and a contact element 14 movable within the housing between a stable first position and a second position in which the contact element electrically connects two fixed contact elements secured to the housing. The movable contact element responds to tilting of said housing beyond a predetermined critical angle, with respect to the vertical, by flipping from the stable first position through an unstable position (FIG. 2) into a second position (FIG. 3) which is stable. Unlike prior art tilt-actuated switches, this improved switch applies sufficient force against the fixed contacts, even when the tilting is gradual, to assure reliable electrical contact, necessary for applications such as a 'dead-man-switch' in a portable radio transceiver.
