Abstract
The utility model relates to an on-site/remote double-control switching device, which comprises a double-throw switch and a relay, wherein the double-throw switch is inlaid on the front side of a casing, the relay is arranged in the casing and the casing is provided with four input or output wire connecting terminals. The input terminal of the double-throw switch is connected with an input wire connecting terminal, one manual contact of the double-throw switch is connected with a normally closed contact of the relay, and the other manual contact of the double-throw switch is connected with a normally open contact of the relay. The other ends of the normally closed contact and the normally open contact are connected with an output wire connecting terminal after connected in parallel, and both terminals of a relay coil are respectively connected with an input wire connecting terminal and an output wire connecting terminal. The utility model integrates a separate previous double-control circuit together and is arranged into a small-size casing structure. The utility model has the advantages of small size, convenient installation and operation and low configuration cost.
Description
Technical field
The utility model relate to a kind of on the spot, remote double control switch device.
Background technology
In many occasions, need carry out on the spot and control in real time at a distance the switch of same power consumption equipment or the break-make of same appliance circuit, implement on the spot at present and at a distance with control, generally adopt the method that sets up control switch and circuit separately, exist switch configuration structure complexity, deployment cost height, inconvenient problem with use.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, and deployment cost is low, easy to use on the spot, remote double control switch device.
The technical scheme that realizes above-mentioned purpose is: a kind of on the spot, remote double control switch device, include commutator and relay, its commutator is embedded in the front of a housing, and relay is installed in the housing, and housing is provided with four binding posts of input and output; The input of its commutator connects an input wires terminal, one manual contact of commutator is connected with the normally-closed contact of relay, another manual contact of commutator is connected with the normally opened contact of relay, relay is normally closed, connect an output wiring terminal after the other end parallel connection of normally opened contact, and two terminals of relay coil connect an input wires terminal and an output wiring terminal respectively.
Two control circuits that the utility model will set up separately in the past integrate, and are arranged to a small-sized shell assembling structure, and it is little, easy to install and use to have a volume, the characteristics that deployment cost is low.
