A multi-pole toggle switch achieves sub-miniature dimensions by mounting the four see-saw contacts, four stationary contacts and four actuating pads in two parallel, linear rows, each row on an opposite side of the path of the tip of the toggle lever plunger within the switch housing. A single actuator block carries the four pads and pressure is applied by a single spring from the plunger tip to the sliding block, then to the pads and then to the see-saw contacts. A depending tongue on the block slides in a groove in the base to form a moving insulation barrier between the rows of contacts.
