A non-contact switch and a non-contact switch control system are provided. The non-contact switch control system includes multiple non-contact switches, each including an infrared light module, a brightness sensing unit, a second switch module and a processing unit. The infrared light module includes a first switch module, transmitting unit and receiving unit. The first switch module has a first switch state. The transmitting unit connected to the first switch module emits infrared light according to the first switch state. The receiving unit receives a reflected light of the infrared light. The brightness sensing unit generates brightness information according to an ambient light. The second switch module has a second switch state. The processing unit is connected with the infrared light module, the brightness sensing unit and the second switch module, and controls the second switch state according to the reflected light and the brightness information.

Non-contact switch and control system thereof

A frame assembly is adapted to be mounted on a substrate having a contact switch. The frame assembly includes a frame body and at least one spring arm. The frame body is adapted to move along an operational direction to be in contact with the contact switch. The spring arms are connected to the frame body and obliquely extend from the frame body to the substrate, so that when the frame body is not pressed by an external force, there is a spacing between the frame body and the contact switch. In this way, the number of parts of a button may be reduced by connecting the spring arms to the frame body. The present invention further provides a button using the above frame assembly.

Frame assembly and button

A non-contact switch control system includes: a switch set, configured to receive a sensing signal from a sensed target, the switch set including a first non-contact switch and a second non-contact switch, the sensing signal including a first sensing signal and a second sensing signal; a storage unit, configured to store a control program; and a processing unit, connected to the switch set and the storage unit and configured to execute the control program and control the switch set based on the sensing signal. The control program includes: determining whether the first non-contact switch receives the first sensing signal and obtaining a first determination result; in the situation where the first determination result indicates 'Yes', determining whether the second non-contact switch receives the second sensing signal and obtaining a second determination result; and in the situation where the second determination result indicates “Yes”, disabling the second non-contact switch.
