<p>A switch reduced in space and cost, specifically, a highly reliable switch free from the possibility of assembled components being disassembled on receiving an impact, wherein a microswitch (4) operated by an operation plunger (2) and an LED (14) are mounted on the same circuit board (5), light from the LED (14) is diffused by the operation plunger (2) to be led to an upper operation surface (10a) and a metal plunger plate (12) is fitted into the inner space of the operation plunger (2), thereby preventing the operation plunger (2) from deflecting toward the inner side thereof due to an impact and preventing the engagement between an engaging hole (3b) of a case (3) and an engaging projection (2a) of the operation plunger (2) from being released.</p> |
