Abstract

PURPOSE:To utilize effective radio waves to operate the circuit efficiently for the user, by performing the press operation by the AND output between outputs of a mechanical press switch and an electronic switch. CONSTITUTION:A mechanical press switch 3 and an electronic press switch 9 are used in a press circuit of a radio transmitter and receiver 2, and outputs of both press switches 3 and 9 pass through an AND circuit 10; and only when both press switches 3 and 9 are operated simultaneously, a press signal is transmitted to the radio transmitter and receiver 2 to transmit radio waves from an antenna 1.
