The utility model relates to the technical field of low-
voltage electric appliances, and particularly discloses a time
relay, a side wall of a housing is provided with a plurality of
light guide holes, an inner side wall of the housing between two adjacent
light guide holes is provided with a barrier strip, a
light guide assembly comprises a plurality of light guide heads, the plurality of light guide heads and the plurality of light guide holes are arranged in a one-to-one correspondence manner, and the barrier strip is arranged on the inner side wall of the housing. The light guide heads are inserted into the corresponding light guide holes, a plurality of indicator lamps are arranged on the circuit board, the circuit board is arranged in the shell and abuts against the barrier strips, the indicator lamps and the light guide heads are arranged in a one-to-one correspondence mode, and the barrier strips are arranged between every two adjacent indicator lamps. A barrier strip is introduced to be arranged between two adjacent indicating lamps, so that optical isolation is realized, mutual interference of light rays of the adjacent indicating lamps is prevented, display of each indicating lamp is ensured to be clear and distinguishable, an operator is helped to quickly and accurately identify the current working stage of the time
relay, and the indicating effect and the distinguishing degree are effectively improved; and meanwhile, the barrier strip can further position the circuit board to ensure the stability and reliability of the structure.
