Non-contact mechanical rickety bridge type magnetic switch

Abstract

The invention relates to a non-contact mechanical rickety bridge type magnetic switch which comprises a rickety bridge, a support lug, an external magnetic toggle switch, a switch guide rail and a guide rail support, wherein strong magnetic steel are bound on the two ends of the rickety bridge, one end is connected to a line through a screw and a terminal and fixed in a sealed compartment housing through the support lug, magnetic steel is arranged in the external magnetic switch, and the magnetic switch slides on the guide rail to the left and right stations to realize on / off of the contacts of the rickety bridge to control on / off of the control circuit. On / off of a circuit can be realized without contacting, and on-off station interlocking is applicable to on-off situations of internal electric appliance systems in a sealed compartment housing used underwater to prevent increasing of wire-through holes in the sealed compartment housing used underwater. The non-contact mechanical rickety bridge type magnetic switch has the advantages of convenient use, simplicity and high reliability.

Description

technical field [0001] The invention relates to a non-contact mechanical swing bridge type magnetic switch, which is suitable for a closed cabin shell used underwater, and can realize the on-off of the internal circuit system of the cabin body without leading wires from the inside of the cabin body to the outside of the cabin body, belonging to machinery, switches technology field. Background technique [0002] The internal circuit of the traditional airtight cabin needs to be connected to the switch from the internal lead wire to the outside. The sealing of the cabin lead wire requires the use of O-rings, gaskets or glue to keep the interior waterproof. The switch also needs to take waterproof measures. However, the prior art has problems such as sealing rings, gasket failures, and aging of glue pots, which bring unsafe factors to the use of the internal circuit of the cabin.
