Abstract
A spring loaded switch which includes a coil spring having hook portions provided at respective ends thereof is first fastened to respective catch portions provided inside the switch frame. Thereafter a slider member having a vertical projection is inserted in the frame so that the projection is opposed to one of the hook portions, whereupon the one hook portion can be removed from the catch portion with which it has been engaged, and onto the projection so that the coil spring now urges the slider member in one direction. Since a coil spring can be fastened to the switch frame first as mentioned above, the coil spring can be thereafter handled very easily.
