Abstract
The problem to be addressed is to provide a highly safe and compact switch that is adapted to improvements in portability, weight reduction and size reduction of machines, or the like. An operating part has a button covering the upper part of a cylindrical housing that receives a downward pushing operation and a rotational operation. A contact unit part has contacts which open by being coupled to the downward pushing operation of the button. A twisting coil spring is disposed on the interior of the button, one end being joined to the housing, and the other end being joined to the button. A latch part disposed to the interior of the twisting coil spring, has a plunger coil spring that expands and contracts in a direction perpendicular to the direction of the downward pushing operation, and when a downward pushing operation is performed on the button, causes a sliding rod to slide along an inner wall of the housing while being displaced in the direction of the downward pushing operation.
