Abstract: The present invention relates to motor safety devices as used in increasing numbers for the killing of engines or disengaging propulsion units from motors, when there are no operators to maintain control of an apparatus or vehicle such as jet-ski, boat, go-kart and the like or personnel to oversee use of a motorised tool or the like. Motor boat operators on a boat have been known to fall overboard without being detected by the operator of the boat. Such runaway boats have been known to seriously injure the operator of the boat in the water since a runaway boat tends to circle back to the place where the operator has fallen overboard. The present invention is also applicable to other types of equipment such as motorised gymnasium equipment, hand operated power tools, such as agricultural and arboriculturist equipment and wood working tools.

Abstract: Angled spring contacts and switches made with contactors containing angled spring contacts are disclosed. The housing for the angled spring contacts has a generally cylindrical shape. The contacts are contained within the housing with their ends extending from the housing on either side. The contacts are formed by making bullet-shaped internal contacts that are joined by a spring. The spring is mounted to the two contacts to urge the two contacts away from each other at an angle to a longitudinal axis of the housing. This angle forces contact between each contact and the housing in at least two places, thus creating redundant paths between the contacts. Switches, such as plunger switches having a normal or OFF position, and an actuated or ON position, may be made with one or more angled spring contacts. The contacts have separate surfaces for electrical conduction and for arcing.

Abstract: A switch is disclosed having a switch housing defining a housing interior and an access opening that extends through a wall of the housing to the housing exterior. An actuator assembly including a shaft constrained by said housing moves along a path from a normal position to an actuated position as well as a momentary position. The shaft has an actuating portion which extends outwardly from the housing interior through the access opening. A shaft body inside the housing including a generally planar contact support hat supports a number of switch contacts. A housing base positions a number of terminals having conductive surfaces for biased engagement with selected switch contacts to form an electrical path between terminals when the actuator assembly is in one of either the normal, actuated or momentary positions.

Abstract: There is disclosed a paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch “on” or “off”. The lower edge of the paddle pivots in and out about its upper edge. The switch includes articulated driver means coupled to be driven by the rocker paddle. When the rocker paddle is pushed in, it urges the articulated driver means to rotate a cam means in a first, clock wise direction, or a second, counter clock wise direction. Alternate rotation of the cam drives a slider member having a cam follower back and forth along a linear axis. A shaped leaf spring cooperates with the cam follower to assist in the movement of the slider and determines its rest positions. An indicator such as an LED is used to indicate the state of conduction of the switch. When the rocker paddle is released, it is biased by a spring to pivot back to its initial position.

Abstract: There is disclosed a paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch “on” or “off”. The lower edge of the paddle pivots in and out about its upper edge. The switch includes articulated driver means coupled to be driven by the rocker paddle when it is depressed and to urge the rocker paddle back to its out position. When the rocker paddle is pushed in, it urges the articulated driver means to rotate a cam means in a first, clock wise direction, or a second, counter clockwise direction. Alternate rotation of the cam drives a slider member having a cam follower back and forth along a linear axis. A shaped leaf spring cooperates with the cam follower to assist in the movement of the slider and to determine its rest positions. An indicator such as an LED is used to indicate the state of conduction of the switch. When the rocker paddle is released, it is biased by the articulated drive means to pivot back to its initial position.

Abstract: An electrical switch includes an operating member carrying moving contacts which face, in opposite directions, two rows of fixed contacts. The operating member moves the moving contacts into and out of contact with the fixed contacts. Each moving contact may have opposite ends for contacting two adjacent fixed contacts on a corresponding side of the operating member. Springs provided between the moving contacts and corresponding side of the operating member bias the contact ends into contact with the corresponding rows of fixed contacts.

Abstract: A doze alerting device includes a casing, an earplug and an electronic operating circuit. The earplug is insertable into either the left or right ear of a user to locate the casing at a desired angular position. The circuit incorporates an audio generator for generating a doze-alert audio signal and a gravity switch for triggering the generator. The switch has first and second contacts closing to trigger the generator, with the second contact being movable under the influence of gravity along a path towards and away from the first contact. The path is fixed relative to the casing so that the switch provides a trigger signal when the casing moves from a first angular position corresponding to an upright position of the head when the user is looking straight ahead to a second angular position corresponding to a dipped position of the head when the user starts to doze.

Abstract: An electronic switch includes a rigid base, a circuit board supported by the base which includes an aperture therethrough defined, at least in part, by spaced apart conductive terminals of an electrically conductive circuit, a resiliently flexible casing attached to the base and overlying the circuit board, and a plunger attached to the casing and extending therefrom through the circuit board aperture. The plunger includes a conductive portion which is adjacent to the casing, and a non-conductive portion. The casing is resiliently biased so as to normally position the plunger such that the non-conductive portion thereof extends through the circuit board aperture. Depression of the casing, however, places the conductive portion within the aperture and into contact with the spaced apart conductive terminals to close the electrically conductive circuit. The electronic switch may be utilized in connection with, for example, a drowsiness warning device which includes a band securable about a wearer's neck.

Abstract: A low profile, push-pull, jumper switch that relies on movement of an electrically-insulating switch housing to make and break the connection between two contact members mounted on the surface of a PCB or other substrate. The only metal used are the two contact members and a fixed wire in the housing. The wire is forced into contact with the contact members to electrically interconnect them by movement of the housing when placed in its closed-switch position. In a preferred embodiment, the two contact members are identical and are each constituted of a one-piece U-shaped metal member, with the U-bight depending from the housing and configured to be solderable to the PCB pads or through-holes and thus being fixed. The contact members are configured to latch the housing in its open-switch position or closed-switch position. The switch lends itself to SMT applications.
