PURPOSE: An integrated-type motion sensing switch is provided to integrate components in order to reduce the overall size, thereby being mounted in a small mounting space of a portable device. CONSTITUTION: A light receiving element(20) is mounted on a base. Multiple LED chips(30) are arranged apart from each other around the light receiving element and emit light upward. A partition wall(40) is formed between the LED chips and the light receiving element. A block cover(60) is arranged at the top of the LED chips, the light receiving element, and the partition wall. The block cover covers an adjacent part of each LED chip to the light receiving element. A cover(70) mounted at the base covers all of the LED chips, the light receiving element, the partition wall, and the block cover. A control part activates the LED chips.
