Abstract
A condition-sensing switching device is disclosed having a plurality of active switch elements which are not symmetrical with the line of action of the condition-sensing actuator. A dummy element is provided to establish symmetry and produce a balanced condition on the switch actuator. The switch elements and dummy element are arranged so that no resilient forces are applied to the actuator during a portion of the actuator movement and the resilient forces on each element simultaneously are applied in a balanced manner during actuator movement to ensure that the forces on the actuator are balanced in all positions of the actuator. An adjusting screw is provided to adjust the force of one spring to ensure that absolute balance is achieved.
