摘要:
A push button kind of switch has an elongate stem (7) mounting a cap member (14) and engaged at its lower end in a member (4) retained in a housing (2) and biassed upwardly by a spring (5). A switch member (1) comprising a diaphragm and contacts is operated upon downward movement of the elongate stem (7) by a cushion member (6). Tactile indication of switch operation is given by a profiled portion (15) of the stem (7) co-operating with spring biassed balls (13) in bores (11) in a housing (10). The springs (12), balls (13) and profiled portion (15) provide a high initial resistance to axial movement of the stem (7) followed by rapid collapse and virtually no resistance.

A power generation apparatus can obtain an amount of generated power required for desired signal processing. A wireless switch includes a cover member, a button member, a first plunger, a second plunger, a trigger spring, a return spring, a shaft, a housing, and a power generation module. An intermediate member constituted of the first plunger, the second plunger, the trigger spring, the return spring, and the shaft is connected between the button member and the power generation module. The intermediate member prevents a position of the shaft making contact with the power generating shaft of the power generation module from changing, and causes stress to build up in the trigger spring, until a movement distance of the button member reaches a predetermined distance. The intermediate member releases the stress built up in the trigger spring and pushes the power generation shaft with the shaft using the released stress upon the movement distance of the button member reaching the predetermined distance.

The invention proposes a switch comprising an actuation member in the form of a pushbutton (18) comprising an actuating portion (28) being arranged, when an external force is applied to the pushbutton (18), to be moved vertically relative to the housing between a pushbutton upper position and a pushbutton lower position, said pushbutton (18) and a tilting driving member (84) forming a movable mechanical assembly, characterized in that it comprises electrical switching means (100, 200) for generating signals representative of changes of position of the one (18) and/or of the other (84) of the two components of the movable assembly, said electrical switching means including a sensing switch (100) for sensing the changes of position of the pushbutton (18) between its upper position and its lower position, and a detecting switch (200) for detecting the changes of position of the tilting driving member (84) between its upper position and its lower position.
摘要:
Eine Vorrichtung für das Ein- und Ausschalten eines Elektromotors, insbesondere eines Elektrowerkzeugs, besteht zur Erzielung eines Kontaktdrucks, der unabhängig von der Schaltbetätigung ist, aus einem Gehäuse (17), in dem voneinander isoliert jeweils über eine in Schließrichtung vorgespannte schwenkbare Kontaktbrücke (11, 12) schließbare Anschlußkontaktpaare (13 - 16) angeordnet sind; einem Kontaktschieber (18), der im Gehäuse (17) geführt und in AUS-Stellung der Kontaktbrücken (11, 12) vorgespannt ist; einem für jede Kontaktbrücke (11, 12) vorgesehenen Schwenkorgan (24, 25), das über einen Arm (22, 23) an dem Schaltschieber (18) angelenkt ist und dessen Drehachsen (26, 29) in dem Gehäuse (17) verlagerbar geführt und mit einer Zugfeder (28) verbunden sind, wobei die Schwenkorgane (24, 25) in unterschiedlichen Winkelstellungen (α, β) einen Kontaktbrücken-Steuerhebel (32, 33) aufweisen, und wobei durch Betätigen des Schaltschiebers (18) beide Schwenkorgane (24, 25) derart verschwenkbar sind, daß die Kontaktbrücken (11, 12) nacheinander durch sprunghafte Verlagerung wenigstens einer Schwenkorgandrehachse (29) zum Schließen unter Wirkung der Kontaktschließfeder (31) freigebbar und gegen die Wirkung der Kontaktschließfeder (31) aufstoßbar sind.

摘要:
The invention relates to a portable communication device with an external housing (1) containing at least a mechanical switch (2a; 2b) and at least one key (3) for actuation of said mechanical switch (2a; 2b), said key comprising an actuation surface (30) which protrudes from said external housing through an aperture (10), and the mechanical switch being able to be actuated by swiveling of the key (3) around an axis (XX') substantially perpendicular to said actuation surface. According to the invention said key is made of plastic material and comprises, in its thickness and behind said actuation surface, at least one emerging slit (31a; 31b) extending substantially parallel to said actuation surface.
