An omnidirectional tilt switch includes an enclosure for a gravity response conductive ball. An annular shelf surrounds a central depression where at least one switch contact passing into the housing is exposed. The shelf is operable to support the ball in a position resting against a cup-shaped portion of the switch housing, with the ball centroid located within a imaginary right cylinder having the inner shelf periphery as a base. In response to tilting of the switch, the ball is movable away from the cup-shaped housing to the depression where it engages the aforementioned contact and closes a circuit between that and another contact. A switch holder mounts the switch on a substrate located, for example, in an electro-optical display-type watch. The holder includes a base with a positioning edge or surface and tabs for securing the base to the substrate. Remote from the positioning edge or surface, the switch is supported at an angle relative to the positioning edge or surface.

A tilt switch comprising: a gravity responsive conductive ball; housing means defining an enclosure for said gravity responsive conductive ball and including at least one portion of insulative material; inwardly extending annular shelf means in said enclosure adjacent one end of said housing means; means defining a depression within said enclosure adjacent said one end of said housing means and surrounded by said annular shelf; contact means including at least one switch contact extending through said at least one portion of insulative material of said housing means and exposed at said depression and further including at least one additional switch contact located within said enclosure and insulated from said at least one switch contact: said annular shelf means being operable to support said conductive ball in a position where the ball rests against a portion of said housing means projecting beyond said shelf means, with the centroid of said ball located within an imaginery right cylinder having the inner periphery of said shelf means as a base; and said ball being movable in response to the orientation of said switch, to a position unsupported against said portion of said housing means and in contact with both said at least one contact exposed at said depression and said at least one additional switch contact.
