Description

Piezo Switch for Elevator

The present invention relates to an illumination device of a piezoelectric switch for an elevator, and an illumination device of an piezoelectric switch for an elevator that can obtain different lighting effects by varying the positions of the piezoelectric sensor, the light emitting means and the cover (WINNDOW) to which the light emitting means is irradiated. It is about.

An elevator switch uses a push switch and a capacitive switch. 1 is a view showing a push type switch. Referring to this, there is a clearance 102 between the floor selection switch or the up / down switches 110 and 112 and the panel provided in the elevator panel 100, and the foreign material is inserted into the clearance 102. In this case, the switch keeps the ON state to cause the elevator to operate abnormally, or there is a fear of leakage due to leakage through the gap.

In addition, as shown in FIG. 1B, since the elevator switches 111 and 113 protrude from the panel 101, there is a fear that the user does not intend to turn on an unintended switch.

A method of compensating for the drawbacks of the push switch is a capacitive switch (not shown). The capacitive switch completely blocks the outside and inside of the elevator operation panel to prevent malfunction of the elevator switch due to leakage or foreign material insertion. However, it is disadvantageous to contact human skin to turn on the capacitive switch. There was a problem that the probability of malfunction of the capacitive switch itself was high.

The present invention has been made to solve the above problems, the object is to attach a piezoelectric sensor to the bottom or cover (WINDOW) of the panel, the interior and exterior of the panel is the lighting device of the elevator piezo switch is blocked by the cover Another object of the present invention is to provide an elevator piezoelectric switch lighting device that prevents a user from malfunctioning by making a pressing portion lower than other portions of the panel to turn on the switch (ON). have.
