Abstract: PURPOSE: To facilitate free selection of the location to some extent by a method wherein the kinetic energy of a displacement member which is moved reciprocally when a heavy object passes over a displacement mechanism is converted into the electric energy and outputted. CONSTITUTION: When a vehicle, a human body, etc., passes over a displacement mechanism 100 and a load is applied to an upper plate 110, the upper plate 110 which is at a reference position is made to sink to a lower limit position. When the vehicle, the human body, etc., leaves the displacement mechanism 100, the upper plate 110 is restored to the reference position by the actuation force of a spring part 150. By the reciprocal movement of the upper plate 110, a current is generated in a coil 141 and a battery 200 is charged. The accumulated electric energy is taken out from the terminals of the battery 200 and used as an auxiliary power supply. Therefore, by setting the location region of the mechanism relatively widely, the necessary and sufficient electric energy can be obtained.

Title: Switch construction
Inventor: FURUHATA SHIGEO
IPC: H01H25/00
Filed: 1988-01-18
Abstract: PURPOSE:To enable a unidirectional operation switch to have a plurality of functions by combining the switch with an operation part working in two or more directions. CONSTITUTION:When a vertically operating switch button 1 is pressed, an operation board 7 lowers and presses a micro switch 8, thereby turning a switch ON or OFF. In this case, when released, the vertically operating switch button 1 is returned to an original position due to the force of a spring 3. When a horizontally operation switch button 4 is operated, a slant part at the bottom thereof presses an operation board 7, thereby turning ON and OFF a micro switch. For resetting, the switch button 4 is returned to an original position and the slant part at the bottom thereof does not come to press the operation board 7. Therefore, the switch button 4 is reset with the resetting force of the micro switch 8. According to the aforesaid construction, a unidirectional operation switch can be made to operate in a plurality of directions and in addition, it is possible to obtain different functions such as auto-reset in a certain operational direction and continuous operation in another operational direction.
