Described upper strata conduction masking foil and described lower floor's conduction masking foil form loop by the arcuate socket of the dividing plate relay that contacts with power supply, and masking foil do not contact relay and power supply disconnection are conducted electricity in upper strata conduction masking foil and lower floor.
Further, dividing plate is made up of rubber.
Further, between upper strata conduction masking foil and/or lower floor's conduction masking foil and inflatable packer wall, be provided with multiple projections.
All right, inflatable packer edge is provided with multiple air cavitys, and air cavity is communicated with inflatable packer, and under uniform pressure, air cavity wall is larger than inflatable packer wall deflection.
All right, the supply voltage of relay is less than 36A.
All right, in inflatable packer, punching has inert gas.
The technical solution adopted for the present invention to solve the technical problems provided by the invention is: a kind of cushion type pressure switch is provided, relay-set is set in cushion, size by pressure changes cushion shape, make relay-set energising or power-off, and then make existing relay-set (little circuit arrangement) control domestic circuit, the present invention compared with prior art has the following advantages: make small household appliances (warmer, electric fan) accomplish that people sits and open, people walks to close, and simple in structure, with low cost, be easy to manufacture, be easy to carry, appearance looks elegant, not only practicality but also can be used as was decorated and furniture, just can realize the Kai Heguan to warmer without destroying household electrical appliance wired circuit, owing to directly not contacting appliance switch, do not have Danger Electric shock risk, and tear immediate shipment open, plug and play, be not subject to the restriction of place and external condition, without Switching Power Supply back and forth at a distance, close conveniently electricity, eliminate the electric appliance standby waste of energy causing because of inertia due to people, extend the useful life of electrical equipment, the more important thing is the risk that reduces and eliminate the fire generation causing because of warmer.
