Abstract
A push switch with dual sensing mode including a main socket, a sliding base, a keycap, a sensing circuit board and a touch sensor is provided. The main socket has an opening and a base. The sliding base is slidably fixed in the main socket. The keycap is correspondingly fixed at the upper end of the sliding base. The sensing circuit board is correspondingly installed in the main socket. The touch sensor is disposed in a keycap chamber of the keycap. When a user places his finger on the upper end of the keycap, the touch sensor generates an inductance and causes the sensing circuit board to output a touch signal.
Claims6
A push switch with dual sensing mode, including:
- a main socket, having an opening at the upper end, the main socket having a base fixed at the bottom end of the main socket, a push signal conductor is disposed at the inside bottom wall of the base, the base further having a recovering elastic part, the recovering elastic part having a pressing surface, and the pressing surface facing the push signal conductor without contacting the push signal conductor, when the recovering elastic part is pressed form the upper end and making the pressing surface to contact the push signal conductor, the push signal conductor is turned on to transmit a pressing signal;
- a sliding base;
- slidably fixed in the main socket, the bottom portion of the sliding base having a pusher, the pusher is against the upper end of the recovering elastic part;
- a keycap, correspondingly fixed at the upper end of the sliding base, when the keycap is pressed downward, the sliding base is linked to press the recovering elastic part, the bottom end of the keycap has an opening and is concave inward to form a keycap chamber;
- a sensing circuit board, correspondingly installed in the main socket;
- and
- a touch sensor, disposed in the keycap chamber, the touch sensor having an extending end, the extending end is electrically connected to the sensing circuit board, and thus when a user places his finger on the upper end of the keycap, the touch sensor generates an inductance and causes the sensing circuit board to output a touch signal,
- wherein the push switch is activated to be pressed after outputting the touch signal.
