The switch proper is a horizontal bar sus-pended at the lower end of a wood arm, which in turnis operated in an up-and-down direction by themechanism mounted on the outside of the case. Onclosing the switch, the horizontal bar engages at itsends with the spring clips suspended from the bush-ings and directly undeneath them.
