Abstract

PURPOSE:To make unnecessary a base for carrying a switch thereon so as to make the electronic equipment in the title smaller and lighter and also reduce its cost, by operating a key top which is disposed on an armorning mold base via an elastic portion, thereby performing control in such a way as to allow or stop transmission of electrically to conductive patterns formed in the key top. CONSTITUTION:When the upper face of a key top 14 is pressed, a resin spring 14A is elastically deformed to cause the key top 14 to move downwards. A control button 28A is therefore caused to abut against a protrusion 30A and forced into a switch 28, so that electricity is transmitted to a conductive pattern 24A and a conductive pattern 24B. When the pressing force against the key top 14 is removed, the resin spring 14 is restored from its elastically deformed state, the control button 28A is released from its state in which it is caused to abut against the protrusion 30A, and the control button 28A is caused to protrude from the switch 28, so that electricity is not transmitted to the conductive pattern 24A and the conductive pattern 24B. A base for carrying a switch thereon is thus made unnecessary to reduce the number of components so as to make the equipment in the title smaller and less heavy and also to reduce its cost.
