摘要:
A volume control device mounting mechanism for on-vehicle equipment comprising: a variable resistor having a shaft; a knob mounted to an end of the shaft; a chassis for securing the shaft; a insertion hole formed on the chassis, the shaft being inserted through the hole; and slits formed on the chassis around the insertion hole, whereby mechanical strength of the chassis around the shaft insertion hole is slightly decreased from that of other portion of the chassis. The slits provided on the chassis prevent the volume control knob and the shaft from destruction due to large impact force, thereby the variable resistor as well as the knob and the shaft can be reused and human body of cardriver can be protected from injury.

A means is disclosed for holding an instrument having a knob, in a projected operative position from an instrument panel of a vehicle. The instrument holding means comprises at least one projection, a plurality of bolts screwed into each projection. The bolts have shank portions, respectively, which extend in parallel with each other. A flange is secured to the instrument. Springs mounted around the shank portions are compressed to bias the flange into abutting engagement with the projections.

Mounting means for instruments, switches or the like in road vehicles. The mounting means includes a mounting frame which can be attached to a panel of a road vehicle. A part associated with the instrument, switch or the like is engaged in an aperture in the mounting frame, and the mounting frame and said part include co-acting parts for pivotally interconnecting said part and the frame. In addition, said part and said frame include co-acting releasable catch means positioned in use between the axis about which the part can pivot relative to the frame, and the passenger compartment of the vehicle said co-acting catch means serving to hold the part against pivotal movement relative to the frame until the part has sufficient force applied thereto to release said catch means. Sufficient force is applied to said part for example, in the event of an occupant of the vehicle striking the instrument, switch or the like when the vehicle is involved in a collision, whereupon said catch means is freed, and said part is free to pivot relative to the frame in a direction away from the passenger compartment of the vehicle, thereby minimizing the risk of injury to said occupant of the vehicle.

A short-circuit shutdown switch is disclosed having a load current path and a cutting plunger. The load current path has a separating member with a first predetermined cutting zone, a second predetermined cutting zone, and a central section positioned between the first predetermined cutting zone and the second predetermined cutting zone. The cutting plunger is positioned to cut the first predetermined cutting zone and the second predetermined cutting zone.

A switch body portion attached to a center console includes a dial switch. The switch body portion is held on the side of the enter console for attachment through engaging of front engagement portions and a rear engagement portion. When an external force having a specified magnitude or greater acts on the dial switch from the rear, the engaging of the front engagement portions is released, so that the switch body portion falls off downward, rotating around the rear engagement portion. Accordingly, an impact which may occur when some object hits against the dial switch projecting upward from an upper face of the center console from the rear can be properly absorbed.

A device and method that contains an electro-mechanical break away sensor that de-energizes power or stops the flow of electricity to a pole upon a vehicle colliding with the pole or otherwise activation of the sensor. The sensor is omni directional and operates regardless of direction of impact from the vehicle or activation and has the ability to disconnect power when the pole falls due to a shear impact such as when there is a collision or the pole falls due to tension created by wind or weight failure. The sensor may also be activated by an authorized user such as one that is performing maintenance on the pole.

An elevated light apparatus for an airport runway light system comprises a mast mounted to a base plate, which is attached to a base-cup. The mast can be designed with a hollow configuration to allow internal electrical connection between a light source in a light assembly and an isolation transformer in the base-cup. The mast can include a frangible break joint that cleanly separates the mast from the base plate. A safety power cut-off switch can be fixed into the base plate on the base-cup. The power cut-off switch can be positioned in the frangible break joint so that a switch button can be held closed by a breakaway portion of the frangible break joint. In the event of mast breakage, the switch button can be released to open electrical circuits for quick disconnection of the electrical connection.

A mode switch assembly of an automobile having an impact/load absorbing apparatus includes a housing disposed in a center facia panel in an automobile, a circuit board installed in the housing, on which a switch having a shaft is installed, a support portion for supporting the circuit board a distance from the housing, a knob on the shaft and protruding from the center facia panel, and an impact/load absorbing unit so the knob and the shaft retract with respect to the center facia panel, breaking at least one side of the circuit board or the housing, when an impact/load is applied to the shaft through the knob.

A rotary switch adapted to be integrated into a push-to-start electrical control for a clothes dryer or the like employs a rotatable and axially translatable operator having an outwardly extending arm supporting a downward finger which travels across a pivotally mounted and downwardly arcuate lever to open and close contacts mounted on one end of the lever with rotation of the operator. Stops on rotation ensure that the finger is positioned on the lever so as to provide positive biasing of the operator to its end positions. The armature of a relay is actuated by a second arm from the operator contacting the armature within a triangle formed by the electromagnet coil and pivot supports preventing de-stabilization of the armature by the operator. Assembly of the relay to a base of the switch is provided by integrally molded hooks receiving tabs which cover holes necessary for the hook's manufacture. The operator is supported in a socket having a thin bottom wall that breaks free upon axial impact against the operator such as otherwise would be expected to damage the integrity of the switch housing.
