Stabilizer Disconnect switch for electrical applicances

#The invention relates generally to electrical appliances, such as electrical heating devices, and pertains more particularly to a stabilizer for switches interrupting the supply of power to the appliances.

#Electrical appliances, such as electrical heating devices, are known to include a switching device in the circuit of the appliances, which, upon assuming a tilting position with an inadmissible angle of tilt, separates the electrical arrangement of the appliances from the source of power and upon returning the appliances to the admissible upright working position switches them on to the source of power.

#Swiss patent specification CH 620047 shows a disconnection switch arranged in the circuit of a heating appliance which serves as stabilizer and displays a switch casing with a fixed contact and a switch spring that is deflected upon the housing inclining from the vertical, and which interrupts an electric circuit. The switch spring is connected by way of a tappet pin to a plate-shaped body freely supported in the switch casing, which plate is tiltable by a suspended weight.

#FIG. 1 shows a sectional side elevation of a stabilizer according to the invention, in the rest position.

#FIG. 2 shows a sectional side elevation according to FIG. 1, with the stabilizer in a tilting position.

#FIG. 3 shows a plan view of a stabilizer according to FIG. 1.

#Referring to FIG. 1, the stabilizer comprises a housing 1 with an outwardly arched housing bottom lb which comprises a central boring la. In the housing, a control ball 4 rests in the boring la in a stable equilibrium position. Above the control ball 4, a hanging shell 5 is provided, which with its shell jacket 5a embraces the control ball 4 at a distance 13 from the surface of the ball.

#The shell 5 is firmly connected to a control piston 6 which with a cylindrical section extends through a boring in a housing cover 14 and with an inner piston surface of an additional piston section arranged on the control piston rests on the housing cover 14. Above the control piston 4, a cylindrical pin 7 is situated in a guide boring 9, linearly movable in a cover mount 8. Above the cylindrical pin 7, two contact springs 2 and 3 are arranged adjoining one another in the rest position, from which connecting springs 10 extend laterally.

#As results clearly from FIGS. 3 and 4 in particular, the cylindrically shaped housing 1 comprises at its upper cylinder jacket edge several detents 12 which in the stop location engage the superimposed housing cover 14 and fasten the latter in a snap-on fashion. As results further from FIGS. 3 and 4, the housing cover 14 additionally comprises a mounting element 11 extending from it at a right angle, which can be provided with borings or appropriate fastening grooves.
