Bus switch with friction loaded actuation lever

Abstract From the Canadian patent

A bus switch alternately couples one of at least two multiple conductor buses into electrical contact with another multiple conductor bus. The bus switch includes a printed circuit board having conductors connected between contacts of a disk switch and bus connector terminals. The disk switch includes stationary and rotatable members the stationary member being, carried by the circuit board and the rotatable member being connected with an actuator for imparting rotation for switching of the disk switch between the multiple conductor buses. The actuator includes a lever confined in a pivot mount being in a fixed space relationship to the circuit board. spring is co-axially carried on a …
