The invention relates to a switching device and a remote control unit using the switching device to be used for operating a variety of electronic products. The invention aims to provide a device and unit which can be miniaturized and which can utilize a high-density components mounting technology. A switch () is disposed inside an inner periphery of the rotary operating part (), and a lever () of the switch () is engaged with a cam () formed at an inner boundary of the operating part (), constituting a switching device (). With this constitution, the switching device and the remote control unit using the device can be provided miniaturized using a high-density components mounting.

Switching device and remote control using the switching device

A push-button switch includes an insulating board, an actuator, an urging body and a push button. The insulating board has plural switch-contacts. The actuator is made of resilient material and includes a base section placed on the board, a primary and secondary actuating sections. Both the sections are disposed above the switch-contacts and linked to the base section via respective linking sections. The urging body has a first end rotatably supported by a supporting section formed on the actuator or another supporting section formed on the insulating board, and has a second end for urging the primary actuating section. The push button depresses a mid-section of the urging body. The structure discussed above allows the push-button switch to have various combinations of operating forces and strokes. The push-button switch and a multiple switch employing this push-button switch can be used in various electronic apparatuses.
