Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: To provide a switch which is easy to operate for a wide range of users, in relation to a wall-mounted switch used in a house or the like. An optical axis formed by a reflection type photoelectric sensor and a reflection plate is arranged in a long direction in a vertical direction to form a switch for performing a detection operation in a long direction.

Description

[Detailed description of the invention]

[0101]

[Technical field to which the invention belongs]

 The present invention relates to a wall-mounted switch that uses a reflective photoelectric switch to turn the switch on and off without contact.

[0092]

[Prior art]

 Conventionally, the switch installed in a house is a switch that is turned on and off by mechanical operation, and the operable range is narrowed, requiring an operating force.

[0093]

[Problems to be solved by the invention]

 With such conventional switches, it is difficult to share one switch when the appropriate operation position and operation force such as wheelchair users, people with physical disabilities, adults and children are different.

[0093]

[Means for Solving the Problems]

 The switch of the present invention enables a switch operation over a long range in the vertical direction by arranging the optical axis of the reflective photoelectric sensor in the vertical direction.

[0056]

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In FIG. 1, reference numeral 1 is a photoelectric switch body, which is installed on the wall surface.

The light projected from the reflection type photoelectric sensor 2 arranged vertically downward is reflected by the reflection plate 3 and received by the reflection type photoelectric sensor 2, and is configured by the control relay unit 4 which receives the detection signal. .

The operation of the photoelectric switch formed as described above will be described. First, when the optical axis emitted from the reflection type photoelectric sensor 2 is blocked by a hand or the like, it is built in the control unit 4 by the detection signal. A relay (not shown) that is turned on reverses the ON or OFF state to perform the switch operation.

Further, the relay (not shown) shown in the above embodiment may be provided with a keep relay to have a memory function.

[0099]

[Effect of the invention]

 As is clear from the above description of the embodiments, according to the present invention, in the photoelectric switch using the reflection type photoelectric sensor as the switch means, the detection operation that is long in the vertical direction is performed, so that it is safe for a wide range of users. As a result, reliable switch operation becomes easy.
