Title:
PUSHBUTTON SWITCH DEVICE
Document Type and Number:
Japanese Patent JP3074671
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reset an operation shaft upward against the pressing operation thereof, and reduce the number of parts for improving assembling workability by providing a reset spring, a loosening prevention part and a stopper part in such a state as integrated with a pushbutton body.
SOLUTION: A pushbutton body 10 is formed out of resin material in such a state as integrated with a reset spring 12, a loosening prevention part 13 and a stopper part 14. When the pushbutton body 10 is mounted, the reset spring 12 comes to have the end 12a thereof in contact with the upper surface of a mounting plate 5, thereby energizing the pushbutton body 10 upward. The loosening prevention part 13 is formed to have a larger diameter than the insertion hole 9 of the mounting plate 5, thereby preventing the lower end of the pushbutton body 10 from being detached from the mounting plate 5. According to this construction, a device to be easily assembled can be provided.
