Abstract: A probe thermostat is shown having a single, stamped metal channel having a first coefficient of expansion coupled to a rod having a second, different, coefficient of expansion. An electrically insulating block is mounted on the channel which in turn cantilever mounts a pair of electrically conductive arms spaced one over the other with electrical contacts disposed on the arms in facing relation to one another. A molded plastic adjustment cam snaps into slots formed in the channel to adjust the position of the lower arm. A hinge formed in the channel and connected to the rod causes movement of the top arm as the temperature of the thermostat changes to cause the contacts to move into and out of engagement with each other.

Abstract: A temperature responsive electric switch is shown having an operating bimetallic member adapted to sense the temperature of a heat source coupled to an over-center switch mechanism and an ambient temperature bimetallic member to maintain a predetermined temperature delta in the operation of a thermostat regardless of changes in ambient temperature.

Abstract: A thermally responsive control especially for a clothes iron combines an adjustable, temperature-regulating thermostat and an over-temperature control for limiting maximum temperature levels on a plastic mounting bracket where the over-temperature control also protects the mounting bracket against damage from overheating.

Abstract: A thermostatic switch is shown having a body supporting a temperature sensing probe formed of a rod of one thermal coefficient of expansion connected to a channel of a different thermal coefficient of expansion. The difference in expansion between the rod channel is translated through a hinge to an overbalance type switch mounted on the body. The temperature at which the switch actuates is adjustable through an element movable toward and away from the switch by a cam mechanism as well as an independent threaded adjustment. The switch is shown in one embodiment as having an integral movable switch arm and loading spring and in a second embodiment as having a discrete movable switch arm and a discrete loading spring.

Abstract: A temperature sensitive probe plug in which connector wires are crimped to the terminals of the plug. The power lead wires can be attached to the connector wires by crimping connectors, the base of the plug beneath the crimping connectors being shaped as anvil portions so that it is merely necessary to insert the wires into the crimping connectors and the application of a crimping tool will crimp the connectors about the wires by the reaction of the tool against the anvil.

Abstract: A motor starting device for de-energizing the starting winding the required motor speed is reached comprising electromagnetic means (3) to urge actuation of the switching means (20,21) and a latch member (10) controlled by a thermal temperature-balanced bimetallic strip (5) to prevent switching until the bimetallic strip (5) reaches a selected temperature through current flow flow therethrough.

Abstract: This invention relates to a thermostatic snap switch and in particular it relates to a switch of the type which has a temperature sensing probe containing an actuating element for the switch.
