PROBLEM TO BE SOLVED: To enable a switch operator to reliably perform switching control even when the operator operates the switch with gloves on. SOLUTION: This switch is provided with an operating part 2, an oscillation circuit part 1a for oscillating a microwave, antennas 1b and 1c which transmit the microwave as a transmitting signal and are arranged adjacently to the operating part 2 so as to receive a reflected wave reflected by a mobile object M advancing toward the operating part 2 as a received signal, a mixer 1d for mixing the received signal with the transmitting signal to output a mixer signal, a signal processing part 1A for detecting the mobile object by a Doppler method on the basis of the mixer signal of the mixer 1d, and a load controlling part 4 for performing switching control of a load L based on the detection results of the mobile object M by the signal processing part 1A. |
