Abstract

An arrangement for regulating the power output of resistive loads or electrical appliances, especially the cooking plates of electric ranges, which includes actuating elements for the switching on and preselection of power stages or steps for the load devices, relays for the supply of power, and incorporating an electronic control circuit for regulating the conductance of electrical power to the resistive loads.

Claims

1. An arrangement for switching control modules which regulate the power output of resistive loads, such as cooking plates of electric ranges, said switch modules including actuating elements enclosed in a housing for activation and preselection of power stages for the resistive loads, with relays for supply of power and an electronic control circuit for regulating conductance of power to the resistive loads;

comprising, in combination;

(a) a plurality of switch modules including actuating elements and relays, said switch modules having a box-like housing having a front and back face, said front face having at least one resilient tab, each said switch module including a printed circuit board with plug connectors for connection to a power supply and signal lines, such that said switch modules are connected through said plug connectors to the signal lines which connect to a remotely located microprocessor arranged in a range timer;

(b) a common electronic control circuit remote from said modules including said microprocessor for said plurality of switch modules; and

(c) a frame unit having spaced openings for fastening said plurality of said switch modules;

wherein said at least one tab of each switch module connects by snap-action to said spaced openings of said frame unit to fasten said switch modules to said frame unit.

2. An arrangement as claimed in claim 1, wherein said frame unit includes a printed circuit board which supports said common electronic control circuit for all of said switch modules.

3. An arrangement as claimed in claim 2, wherein the printed circuit board is attached to and extends perpendicularly from said frame unit.

4. An arrangement as claimed in claim 1, wherein a printed circuit board is attached to the frame unit and has respective terminals thereof connected with the plug connectors for the signal lines of each of the switch modules in said frame unit, said printed circuit board attached to the frame unit being coupled to said common electrical control circuit.

5. An arrangement as claimed in claim 1, wherein each of said switch modules include actuating axles extending from bore openings in said housing, and said resilient tabs inserted into respective openings in the frame unit, and said modules having plug connectors for the signal lines engaging in associated openings in a printed circuit board attached to the frame unit for supporting said common electronic control circuit.

6. An arrangement for regulating the power output of resistive loads, such as cooking plates of electric ranges, including actuating elements for activation and preselection of power stages for the resistive loads, with relays for supply of power and an electronic control circuit for regulating conductance of power to the resistive loads/ comprising, is combination;
