摘要： A control circuit for a lawn tractor having an engine and a power take off driven implement. The control circuit includes an inhibit circuit component for preventing operation of a power take off driven implement with the tractor in reverse. Two versions of the inhibit circuit are disclosed, one grounds an engine magneto and a second disables an electric clutch for coupling the power take off to the driven element. The circuit includes first and second override switches and an override circuit component that allows operation of a power take off driven implement while the lawn tractor is in reverse after the first and second override switches are activated in a proper order by a tractor operator.

摘要： A digital engine operating time measuring apparatus for an internal combustion engine. The apparatus is powered by a magneto of the engine and accumulates engine operating time only when the engine is operating. The apparatus includes power regulation circuitry including a pair of terminals coupled to the engine magneto. The power regulation circuitry converts a time varying electrical signal generated by the magneto when the engine is operating to a low voltage DC signal. The apparatus further includes digital circuitry coupled to an output of the power regulation circuitry for calculating accumulated engine operating time. The digital circuitry is powered by the low voltage DC signal of the power regulation circuitry and only accumulates engine operating time upon sensing the low voltage DC signal. The apparatus further includes a display coupled to the digital circuitry for displaying accumulated engine operating time as calculated by the digital circuitry.

摘要： A magnetic latching switch. The switch includes a pair of switch terminals, a switch actuator, an electromagnet and a biasing member. The switch actuator is manually moveable from a first position where the switch terminals are in a first state to a second position where the switch terminals are in a second state. The electromagnet selectively applies a magnetic field. Applying the magnetic field with the electromagnet when the switch actuator is in the second position maintains the switch actuator in the second position. The biasing member is coupled to the switch actuator such that the biasing member automatically returns the switch actuator from the second position to the first position when the magnetic field is removed.

摘要： A self contained radio frequency identification integrated circuit (RFIDIC) switch. The RFIDIC switch includes a switch housing, a radio frequency identification integrated circuit enclosed in the switch housing and an actuator extending into the switch housing. The RFIDIC is powered by a radio frequency carrier signal. The actuator is movable to a first position and to a second position. The radio frequency identification integrated circuit transmits a signal when said actuator is in one of the positions. Movement of the actuator to the other position alters said signal.

摘要： A trim switch for mounting in an opening in an outboard motor cowl is disclosed. The trim switch includes an outer housing which overlies a rocker assembly. The rocker assembly includes a rocker and a rocker support housing. The rocker support housing defines an interior region in which terminals and a terminal bridging contact are disposed. A cup-shaped waterproof boot overlies the rocker assembly and is sandwiched between the outer housing and the rocker assembly. The boot prevents water from leaking between the rocker and the rocker support housing and provides a positive seal between the outer housing the rocker assembly.

摘要： A safety switch assembly for deactivating a motor vehicle if a user is not positioned on a vehicle seat. The assembly includes a base for mounting a switch, a cover that moves in response to the presence of a vehicle operator on the seat, and an actuator that moves with the cover to open and close switch contacts inside a switch housing. The base is constructed to pass through a cutout in a vehicle seat pan and includes extensions that also pass through the cutout. The projections are inhibited from movement back through the cutout after the base is rotated from an orientation that allows the projections to be inserted through the cutout to an orientation in which the projections overlie the seat pan.

摘要： A switch comprises a plunger, a retainer, a pair of terminals and an electrically-conducting wiper contact having a curved or bent middle portion defining two oppositely directed legs on either side of the middle portion. The retainer cooperates with the plunger to carry the wiper contact as the plunger moves between a normal and an actuated position. The terminals have facing contact surfaces for biased engagement with the portions of the legs exposed by the plunger and retainer to form an electrical path between the terminals when the plunger is in the actuated position. The plunger and the retainer are coupled together by arms which project from either the plunger or the retainer. The wiper contact is secured between the plunger and retainer without the need for forming a central loop in the wiper contact for engagement by the plunger.

摘要： A switch for controlling the operation of a motor boat comprises a cylinder and a key. The key includes a grippable knob and a detachable key actuator which engages a key-receiving member in the cylinder. The knob is turned from a first stable angular orientation (that is, an off-position) to a second stable angular orientation (that is, an on-position) to operate the motor. The knob is also coupled by means of a lanyard to the operator. If the operator falls overboard, the knob will separate from the key actuator and springs located inside the cylinder return the switch to the off-position. The switch also permits the a choke signal to be sent to the motor by pressing inwardly on the knob.

摘要： A safety circuit coupled to an ignition circuit and a magneto coil for disabling an engine that powers a riding lawn mower. The circuit includes a triac which is rendered conductive in response to a sensed unsafe condition. The triac turns on to short the magneto coil and prevent generation of a spark plug energization voltage. A capacitor coupled to the triac gate electrode charges in the event an unsafe condition is sensed and is prevented from charging when operating conditions are safe.
