ABSTRACT A thermally responsive load cycling switch assembly user adjustable for varying the time of cycling current to load connecting terminals and having a contact blade cantilevered from an insulator block pivoted in the switch housing. A bimetal blade actuator means is also cantilevered from the block and includes heater means to cause the bimetal to effect movement of the contact blade. A separate blade spring cantilevered from the block enables the block to be pivotably preloaded. A spring blade is cantilevered from the actuator means to enable separate preloading of the bi-metal for temperature calibration. A flexible jumper blade connects the contact blade to one of two load terminal connectors for series and parallel operation. A manually operated arming switch is series connected between one powerline terminal and one of the load terminals. A stationary contact disposed for closing a circuit with thecontact blade is connected to the opposite powerline terminal. The block, contact blade, actuator means including bi-metal, heater, and the calibration spring jumper are assembled as a unit and pivoted in the housing. The terminal connectors are integrally formed with offset tabs for insertion and snap lockingin grooves in the housing.
