摘要
An infrared momentary-contact switch for a control device of a domestic appliance, has a transmitter which emits infrared radiation and a receiver which receives infrared radiation. The transmitter and receiver are disposed behind a cover through which at least some of the infrared radiation passes. In order to achieve a good ratio of useful signal to interference signal for the momentary-contact switch, the transmitter has an associated first optical fiber element and the receiver has an associated second optical fiber element. The ends of these optical fiber elements which respectively face away from the transmitter and receiver are adjacent one another and adjoin the cover. A control device is also provided.
