| 摘要 |
The present invention discloses a non-contact optical sensor switch assembly of elevators which comprises a plurality of switches equidistantly aligned with each other and disposed on a panel of an elevator, and each switch is an operation button for the elevator; a plurality of optical sensors disposed on the switches, such that before a finger touches the switches, the optical sensor is capable of detecting an approaching finger, and the switches are electrically coupled to a signal detect circuit of the elevator, and the signal detect circuit is coupled to a control circuit of the elevator; thereby, when the optical sensor senses the approaching finger, the optical sensor sends a detect signal to the signal detect circuit and the detect circuit sends the detect signal to the control circuit, such that the control circuit executes the corresponding operation according to an instruction given by pressing the switch.
