KEYPAD
First Claim
1. A keypad, comprising:
- a base, having a through hole;
an actuator, movably located in through hole so as to be moved between an initial position and a pressed position with respect to the base;
a first elastic member, located between and connected to the base and the actuator in order to provide force on the actuator to move the actuator towards the initial position;
a pivotal mechanism, pivotably and linearly movably disposed on the actuator so as to be moved between a withdrawn position and a protruding position; and
a second elastic member, located between and connected to the actuator and the pivotal mechanism in order to provide force on the pivotal mechanism to move the pivotal mechanism towards the protruding position;
wherein, the base has at least one stop block and at least one recess connected to each other on an inner surface forming the through hole, the pivotal mechanism has at least one tooth;
when the actuator is in the initial position, the pivotal mechanism is in the protruding position;
while the actuator is moved to the pressed position from the initial position, the at least one tooth of the pivotal mechanism is stopped by the at least one stop block so that the pivotal mechanism is pivoted and then linearly moved to the withdrawn position, and then the at least one tooth enters into the at least one recess, enabling the pivotal mechanism to the protruding position and press a switch.

Abstract
A keypad includes a base, an actuator, a first and second elastic member and a pivotal mechanism. The base has a through hole. The actuator is located in through hole to be moved between initial position and pressed position. The first elastic member is connected between the base and the actuator. The pivotal mechanism is pivotably and linearly movably disposed on the actuator to be moved between withdrawn position and protruding position. The second elastic member is connected between the actuator and the pivotal mechanism. The base has stop block and recess and the pivotal mechanism has tooth. While the actuator is moved to the pressed position, the tooth is stopped by the stop block so that the pivotal mechanism is pivoted and then linearly moved to the withdrawn position, and then enters into the recess, enabling the pivotal mechanism to the protruding position and press a switch.

10. A keypad, comprising:
-
a base, a actuator, a pivotal mechanism, a first elastic member disposed between the base and actuator for recovering the actuator, a second elastic member disposed between the pivotal mechanism and the actuator for recovering the pivotal mechanism, the top side of the pivotal mechanism is inserted into the actuator, the base has a through hole and at least one stop block which is on an inner surface forming the through hole, the actuator is movably located in the through hole, and the bottom side of the pivotal mechanism has at least one tooth; wherein, when the actuator is pressed, the actuator forces the pivotal mechanism to pivot about a press direction of the actuator, such that the at least one stop block is moved away from the at least one tooth and moved toward the top side of the pivotal mechanism.
