Switch connecting structures include a housing having an insertion hole, and an operation lever slidably mounted in the housing. The operation lever includes a push member protruding from said housing. A resilient contact plate is carried by the operation lever so as to be slidable therewith. A connection terminal is provided having a resilient clamp portion and a contact plate portion. The contact plate portion is inserted into the insertion hole of the housing and extending therewithin over a range of slidable movement of the operation lever so as to be in contact with the resilient contact plate. In such a manner, the clamp portion is connectable to a bus bar for electrical connection of the switch to a circuit.
