Multiple switch arrangement including membrane dome contacts and multi-directional tilt actuator
First Claim
1. A multiple switch device comprising:
- a base which comprises at least two switch units and linkage means placed in at least two positions on said base;
a push button having push members at each respective position opposite to each of said switch units and linkage means at each respective position opposite to each of the linkage means of said base; and
a return means which forces said push button to return to its original position upon releasing a depress force from said push button;
said base and said push button assembled together through a coupling between said linkage means of the base and said linkage means of the push button, so as to allow a vertical movement of said push button, andsaid linkage means of the base and of the push button are arranged so as to satisfy a formula of h≦
k, where k is the distance between the center of said push button and each of said push members and h is the distance between the center of said push button and fulcrum of a seesaw motion of the push button measured along the line connecting the center of said push button and each of said push members.

Abstract
A multiple switch device comprises a base having at least two switch units and supports with pawls placed on the tips of the pawls, a push button having at least two push members and supports with pawls placed on the tips of the pawls, and a spring for returning the push button to its original position. The base and the push button are assembled together through a coupling between the pawls of the supports of the base and the pawls of the supports of the push button. The push button moves in a seesaw-like motion, the fulcrum of which is derived by the two adjacent supports. The push members and the supports are arranged so that the fulcrum position is situated in the same or inside position of the push members.

9. A multiple switch device comprising:
-
a base which comprises at least two switch units and a linkage means placed in at least two positions on said base; a push button comprising push members at each respective position opposite to each of said switch units and a linkage means at each respective position opposite to each of the linkage means of said base; a return means which forces said push button to return to its original position upon releasing a depress force from said push button; a ring-like knob arranged outside the circumference of said push button, said ring-like knob provided with a knob-placed linkage means; a linkage means for the knob arranged on said base at positions opposite to said knob-placed linkage means; a rotational angle detecting means for detecting rotational angles of said ring-like knob; and a rotational return means for returning said ring-like knob to the original position thereof upon releasing a rotational operation; said base and said push button assembled together through a coupling between said linkage means of the base and said linkage means of the push button, so as to allow a vertical movement of said push button, and said base and said ring-like knob assembled together through a coupling between said linkage means for the knob on the base and said knob-placed linkage means to allow a rotational movement of said ring-like knob. - View Dependent Claims (10, 11, 12)
